Abstract
Melanoma represents a public health issue. One of the biggest goals of current research is to develop new therapeutic options for patients affected by this aggressive tumor. We conducted a retrospective study including 105 patients diagnosed with cutaneous and ocular melanoma, with stages varying from pT1a to pT4b and pT4e, respectively, and we performed immunohistochemistry reactions with the new potential prognostic marker, VISTA (V-domain Ig suppressor of T cell activation). We quantified the expression by applying the H-score adapted for VISTA and divided the patients, based on the median value, into groups that presented high, low, and negative expression. Therefore, we obtained 65 cases with positive expression for cutaneous melanoma and 8 cases with positive expression for ocular melanoma. Forty-one cases presented high expression in cutaneous melanoma and three cases presented high expression in ocular melanoma. In cutaneous melanoma, analytic statistics showed that VISTA expression was associated with a high Breslow index, high mitotic count, high Ki67 expression, and advanced clinicopathological stage. The majority of ocular melanoma cases demonstrating a positive reaction were classified as stage pT3, whereas earlier stages showed a negative reaction. Our findings underscore a significant correlation between VISTA expression and key prognostic factors in melanoma. Looking ahead, the prospect of future randomized studies holds promise in corroborating the clinical relevance of our findings. By further elucidating the intricate relationship between VISTA expression and melanoma progression, new treatment strategies could be found, improving patient outcomes in this challenging neoplasm.

Abstract
Basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) are the most frequently occurring non-melanocytic skin cancers. The objective of our study is to present the pathophysiology of BCC and cSCC and its direct relationship with the histopathological diagnostics and the differential diagnostics of these types of cancer, based on the morphological characteristics, immunohistochemical profile, and genetic alterations. The qualitative study was based on emphasizing the morphological characteristics and immunohistochemistry profiles of BCC and cSCC and the differential diagnostics based on the tissue samples from the Clinical Pathology Department of Mures Clinical County Hospital between 2020 and 2022. We analyzed the histopathological appearances and immunohistochemical profiles of BCC and cSCC in comparison with those of Bowen disease, keratoacanthoma, hyperkeratotic squamous papilloma, metatypical carcinoma, pilomatricoma, trichoblastoma, Merkel cell carcinoma, pleomorphic dermal sarcoma (PDS), and melanoma. Our study showed the importance of the correct histopathological diagnosis, which has a direct impact on the appropriate treatment and outcome for each patient. The study highlighted the histopathological and morphological characteristics of NMSCs and the precursor lesions in HE and the immunohistochemical profile for lesions that may make the differential diagnosis difficult to establish.

Abstract
Psoriasis is a chronic immune-mediated disease, linked to local and systemic inflammation and predisposing patients to a higher risk of associated comorbidities. Cytokine levels are not widely available for disease progression monitoring due to high costs. Validated low-cost and reliable markers are needed for assessing disease progression and outcome. This study aims to assess the reliability of blood-count-derived inflammatory markers as disease predictors and to identify prognostic factors for disease severity. Patients fulfilling the inclusion criteria were enrolled in this study. Patients were divided into three study groups according to disease severity measured by the Body Surface Area (BSA) score: mild, moderate, and severe psoriasis. White blood cell count (WBC), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), derived neutrophil-to-lymphocyte ratio (d-NLR), systemic immune index (SII), systemic inflammation response index (SIRI), and aggregate index of systemic inflammation (AISI) positively were correlated with disease severity (p < 0.005). d-NLR, NLR, and SII are independent prognostic factors for mild and moderate psoriasis (p < 0.05). d-NLR is the only independent prognostic factor for all three study groups. Moderate psoriasis is defined by d-NLR values between 1.49 and 2.19. NLR, PLR, d-NLR, MLR, SII, SIRI, and AISI are useful indicators of systemic inflammation and disease severity in psoriasis.

Abstract
INTRODUCTION Immunohistochemistry (IHC) for p16INK4A (p16) is a reliable surrogate test for the presence of a high-risk, potentially transformative human papillomavirus (HPV) infection in precursor and malignant lesions of the cervix. The purpose of this study was to evaluate changes in cervical cells caused by persistent HPV infection, by IHC (p16 protein) by comparison with HPV genotyping. PATIENTS, MATERIALS AND METHODS The study included female patients aged between 26 and 57 years who presented to a public hospital, with complaints related to the genital area, namely vaginal bleeding and dyspareunia. After selecting the patients, samples were subjected to cytological testing and IHC for p16 and for the determination of HPV types. RESULTS The relationship between HPV status and p16 status was statistically significant (p=0.0001), of the 41 patients, 53.7% were HPV positive, respectively 56.1% were p16 positive, the agreement relationship between the two indicators was very high (weighted kappa: 0.951). The clinical performance of CINtec® PLUS triage for p16 shows a high positive predictive value (PPV) and a high negative predictive value (NPV) of 95.7% and 100%, respectively, as regards HPV. CONCLUSIONS The p16 marker (CINtec® PLUS) can be used as a prognostic biomarker and provides clinical usefulness through increased sensitivity (Se) and specificity (Sp) in the triage of women at risk of developing precancerous lesions, compared to cytology that is based on morphology, but has a rather low Se and high Sp, while HPV testing is very sensitive but slightly more specific.

Abstract
The placenta, the foremost and multifaceted organ in fetal and maternal biology, is pivotal in facilitating optimal intrauterine fetal development. Remarkably, despite its paramount significance, the placenta remains enigmatic, meriting greater comprehension given its central influence on the health trajectories of both the fetus and the mother. Preeclampsia (PE) and intrauterine fetal growth restriction (IUGR), prevailing disorders of pregnancy, stem from compromised placental development. PE, characterized by heightened mortality and morbidity risks, afflicts 5-7% of global pregnancies, its etiology shrouded in ambiguity. Pertinent pathogenic hallmarks of PE encompass inadequate restructuring of uteroplacental spiral arteries, placental ischemia, and elevated levels of vascular endothelial growth factor receptor-1 (VEGFR-1), also recognized as soluble FMS-like tyrosine kinase-1 (sFlt-1). During gestation, the placental derivation of sFlt-1 accentuates its role as an inhibitory receptor binding to VEGF-A and placental growth factor (PlGF), curtailing target cell accessibility. This review expounds upon the placenta's defining cellular component of the trophoblast, elucidates the intricacies of PE pathogenesis, underscores the pivotal contribution of sFlt-1 to maternal pathology and fetal safeguarding, and surveys recent therapeutic strides witnessed in the past decade.

Abstract
Psoriasis is an immune-mediated, chronic disorder that significantly alters patients' quality of life and predisposes them to a higher risk of comorbidities, including liver fibrosis. Various non-invasive tests (NITs) have been validated to assess liver fibrosis severity, while blood-count-derived inflammatory markers have been proven to be reliable in reflecting inflammatory status in psoriatic disease. The fibrosis-4 (FIB-4) index became part of the newest guideline for monitoring psoriasis patients undergoing systemic treatment. Patients with psoriasis vulgaris and fulfilling inclusion criteria were enrolled in this study, aiming to assess for the first time in the literature whether such inflammatory markers are useful in predicting liver fibrosis. Based on internationally validated FIB-4 index values, patients were divided into two study groups: a low risk of significant fibrosis (LR-SF) and a high risk of significant fibrosis (HR-SF). Patients from HR-SF were significantly older and had higher values of the monocyte-to-lymphocyte ratio (MLR) (p < 0.001), which further significantly correlated with fibrosis severity (p < 0.001). Platelet-to-lymphocyte ratio (PLR), systemic immune inflammation index (SII), platelet-to-white blood cell ratio (PWR), and aggregate index of systemic inflammations (AISI) significantly correlated negatively with liver fibrosis (p < 0.001). PWR proved to be the most reliable inflammatory predictor of fibrosis severity (AUC = 0.657). MLR, PWR, and AISI were independent inflammatory markers in multivariate analysis (p < 0.001), while the AST to platelet ratio index (APRI) and AST to ALT ratio (AAR) can be used as additional NITs for significant liver fibrosis (p < 0.001). In limited-resources settings, blood-count-derived inflammatory markers such as MLR, PWR, and AISI, respectively, and hepatic indexes APRI and AAR prove to be of particular help in predicting significant liver fibrosis.

Abstract
Monosodium glutamate (MSG) is the sodium salt of glutamic acid (GLA), used as a flavour enhancer. MSG is considered a controversial substance. It is incriminated in disturbing the antioxidant system, but also has beneficial effects, as GLA metabolism plays a crucial role in homeostasis. This study highlights which positive or negative aspects of MSG sub-chronic consumption are better reflected in subjects potentially affected by advanced age. Daily doses of MSG were administered to four groups of two-year-old Wistar rats for 90 days: (I) 185 mg/kg bw, (II) 1500 mg/kg bw, (III) 3000 mg/kg bw and (IV) 6000 mg/kg bw, compared to a MSG non-consumer group. Aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, direct and total bilirubin, total cholesterol, triglycerides, creatinine and urea levels were analysed; stomach, liver and kidney samples were subjected to histopathological analysis. Although, in most cases, there were no statistical differences, interesting aspects of the dose-effect relationship were observed. After MSG sub-chronic consumption, the positive aspects of GLA seem to be reflected better than the negative ones. The hormesis effect, with low-level reactive oxygen species' protective effects and GLA metabolism, may represent the hypothesis of a potential defence mechanism triggered by MSG sub-chronic consumption in ageing rats.

Abstract
BACKGROUND/AIM A real challenge for patients with rheumatoid arthritis (RA) and rheumatologists is primary nonresponse status (PNRS) or secondary nonresponse status (SNRS) to various therapies. Despite their detrimental influence on patient life quality, PNRS and SNRS have no accurate definition and no early predictive criteria for their development exist. Patients with RA under 40 years of age are rare, hence PNRS and SNRS data for this age group are scarce. This study examined the PNRS and SNRS according to sex, age, BMI, therapy type, and duration. PATIENTS AND METHODS Retrospectively, 115 patients with RA having PNRS and/or SNRS were stratified by age (22-39, 40-59, and 60-81). The association between body mass index (BMI), proinflammatory cytokines inhibitors, JAK inhibitors, and TNF-alpha inhibitors, sex, age, and PNRS and SNRS was examined. RESULTS All three proinflammatory cytokine inhibitors (rituximab, tocilizumab, and abatacept) were associated with PNRS and SNRS in women with a high BMI aged 40-59 years. Abatacept-related PNRS and SNRS was significant in women with normal BMI aged 60-81 years. Adalimumab, infliximab, and golimumab affected SNRS differently in women with normal BMI aged 22-39 years and women with high BMI aged 60-81 years. Etanercept and infliximab were associated with SNRS status in men with high-BMI aged 40-59 years. CONCLUSION PNRS and SNRS development in patients with RA is significantly influenced by age, sex, and BMI, but most importantly is closely and differentially related to therapy type and duration.

Abstract
BACKGROUND The correlation of the inflammatory profile with the severity of the disease in neoplastic patients with SARS-CoV-2 infection was addressed. METHODS A database of 1537 patients hospitalized in the pneumology department was analyzed. After applying the inclusion and exclusion criteria, 83 patients (67% males, 33% females) were included. RESULTS Most of the analyzed patients were hospitalized with a moderate form of disease, explaining the significant percentage of 25% mortality. The frequency of the type of neoplasm was higher for lung cancer, followed by malignant colon tumor. We identified a significant association between the increased value of ferritin (p < 0.0001, OR = 22.31), fibrinogen (p = 0.009, OR = 13.41), and C-reactive protein (p = 0.01, OR = 7.65), respectively, and the level of severity of COVID-19. The results of the univariate logistic regression analysis for predicting the severity of the disease revealed that the increased values of ferritin (p = 0.001, OR = 22.31) and fibrinogen (p = 0.02, OR = 13.41) represent a risk for a serious negative prognosis of COVID-19. CONCLUSIONS Our study demonstrated that the value of the analyzed inflammatory parameters increased in direct proportion to the severity of the disease and that higher values were associated with increased mortality in the study group.

Abstract
Cancer arising from adenomyosis is very rare, with transformation occurring in only 1% of cases and in older individuals. Adenomyosis, endometriosis and cancers may share a common pathogenic mechanism that includes hormonal factors, genetic predisposition, growth factors, inflammation, immune system dysregulation, environmental factors and oxidative stress. Endometriosis and adenomyosis both exhibit malignant behaviour. The most common risk factor for malignant transformation is prolonged exposure to oestrogens. The golden standard for diagnosis is histopathology. Colman and Rosenthal emphasised the most important characteristics in adenomyosis-associated cancer. Kumar and Anderson emphasised the importance of demonstrating a transition between benign and malignant endometrial glands in cancer arising from adenomyosis. As it is very rare, it is difficult to standardize treatment. In this manuscript, we try to emphasize some aspects regarding the management strategy, as well as how heterogenous the studies from the literature are in terms of prognosis in both cancers that develop from adenomyosis or those that are only associated with adenomyosis. The pathogenic mechanisms of transformation remain unclear. As these types of cancer are so rare, there is no standardised treatment. A novel target in the diagnosis and treatment of gynaecological malignancies associated with adenomyosis is also being studied for the development of new therapeutic concepts.

Abstract
Myocardial infarction (MI) leads to irreversible ischemic damage of the heart muscle and is the leading cause of heart failure. The ischemic cardiac injury triggers a potent local and systemic immune response. In the acute phase post-MI, neutrophils infiltrate the myocardium in large numbers and induce further cardiomyocyte death, expanding the infarcted area. The alarmin S100A8∕A9 is a proinflammatory mediator primarily produced by myeloid cells, with an emerging role in MI. We previously demonstrated that short-term inhibition of S100A8∕A9 during the inflammatory phase of the immune response to MI improves long-term cardiac function. In the present study, we investigated the effects of S100A8∕A9 blockade on myocardial inflammation and post-ischemic myocardial injury in a mouse model of coronary artery ligation. Immunohistochemical (IHC) staining revealed that the presence of S100A9 is strongly correlated with neutrophil infiltration in the myocardium on days 1 and 3 post-MI. A 3-day treatment with the S100A8∕A9 blocker ABR-238901 starting immediately after MI decreased the number of neutrophils and S100A9 presence in the myocardium and had a positive impact on cardiac damage, reducing infarction size. These findings promote S100A9 as an IHC biomarker of neutrophil infiltration and a promising immunomodulatory target to regulate neutrophil recruitment, reduce ischemic injury and promote long-term beneficial cardiac recovery after MI.

Abstract
Melanoma is a malignant cancer of the skin, the incidence of which has been increasing year by year. This neoplasm has high aggressivity as well as the potential for invasion and metastases. Multiple factors related to the proliferation of this type of tumor have been identified, such as exposure to ultraviolet (UV) radiation and specific genetic backgrounds. From a histological and cytological point of view, the most common cells that are found in melanoma are epithelioid or spindle cells. To confirm the diagnosis and the melanocytic origin of the tumor, specific and sensitive markers are used. Also, observation of the behavior of this cancer, including its proliferative properties, has led to the development of multiple therapies, each of which is characteristic of the pathological stage at the time of diagnosis. While surgery is the most important therapeutic and curative option in cases of melanoma in situ, chemotherapy has been the main treatment for advanced stages of melanoma for many years. However, recently, targeted therapy and immunotherapy have changed the approach to treatment. At present, multiple studies are attempting to obtain further data about the tumor microenvironment and investigating how targeting particular molecules can change the prognosis of patients.

Primary neuroendocrine tumors (NETs) of the breast are considered a rare and undervalued subtype of breast carcinoma that occur mainly in postmenopausal women and are graded as G1 or G2 NETs or an invasive neuroendocrine carcinoma (NEC) (small cell or large cell). To establish a final diagnosis of breast carcinoma with neuroendocrine differentiation, it is essential to perform an immunohistochemical profile of the tumor, using antibodies against synaptophysin or chromogranin, as well as the MIB-1 proliferation index, one of the most controversial markers in breast pathology regarding its methodology in current clinical practice. A standardization error between institutions and pathologists regarding the evaluation of the MIB-1 proliferation index is present. Another challenge refers to the counting process of MIB-1′s expressiveness, which is known as a time-consuming process. The involvement of AI (artificial intelligence) automated systems could be a solution for diagnosing early stages, as well. We present the case of a post-menopausal 79-year-old woman diagnosed with primary neuroendocrine carcinoma of the breast (NECB). The purpose of this paper is to expose the interpretation of MIB-1 expression in our patient’ s case of breast neuroendocrine carcinoma, assisted by artificial intelligence (AI) software (HALO—IndicaLabs), and to analyze the associations between MIB-1 and common histopathological parameters.

Abstract
Primary cutaneous melanoma (PCM) is the most aggressive skin malignancy, with an increasing incidence and significant mortality. Tumoral invasion, expressed as Breslow thickness, is routinely assessed on hematoxylin and eosin (HE), although this stain may sometimes underestimate the tumoral depth. The aim of this study was to compare the efficiency of the immunohistochemical (IHC) markers S-100, SOX10, Melan-A, and HMB-45 with HE for the evaluation of the Breslow thickness and staging of PCM. This retrospective study included 46 cases of PCM diagnosed between 2015 and 2022; for each case, the Breslow thickness using HE, S-100, SOX10, Melan-A, and HMB-45 was measured and the appropriate T category was recorded. The highest values of the Breslow thickness were observed for S-100. However, S-100, SOX10, and Melan-A provided statistically significant higher values of the Breslow thickness compared to HE, but no difference was noted between HMB-45 and HE. S-100 was most frequently involved in increasing the T category (26.1%), the majority of cases being upstaged from T1a to T1b. The IHC markers S-100, SOX10, and Melan-A contributed to better evaluation of the melanoma invasion, especially in thin melanomas, but their impact on staging and consecutive treatment remains to be confirmed by future studies.

Abstract
Dysgerminoma represents a rare malignant tumor composed of germ cells, originally from the embryonic gonads. Regarding its incidence, we do not have precise data due to its rarity. Dysgerminoma occurs at a fertile age. The preferred treatment is the surgical removal of the tumor succeeded by the preservation of fertility. Even if a multidisciplinary team, founded in 2009 by a gynecologist, an oncologist, a pediatric oncologist and a pediatric surgeon, under the guidance of the Malignant Germ Cell International Consortium (MaGIC), studies this type of tumor, issues still remain related to the lack of a randomized study and to both the management and understanding of the concept of OMGCTs (ovarian malignant germ cell tumors). The aim of this review is to present from the literature the various approaches for this type of tumor, and, regarding innovative therapies or possible prevention, which can be applied in clinical practice. Multidisciplinarity and treatment in reference centers have proven their usefulness as well.

Abstract
Ichthyoses are a heterogeneous group of skin disorders featuring erythroderma and generalized scaling. The relationship between ichthyosis and melanoma has not been well-characterized. Herein we present a unique case of acral melanoma of the palm developing in an elderly patient with congenital ichthyosis vulgaris. Biopsy revealed a superficially spreading melanoma with ulceration. To the best of our knowledge, no acral melanomas have been reported so far in patients with congenital ichthyosis. Nevertheless, considering the potential for invasion and metastasis, patients with ichthyosis vulgaris should undergo regular clinical and dermatoscopic screening for melanoma.

Abstract
BACKGROUND Carotid endarterectomy (CEA) is the first-line surgical intervention for cases of severe carotid stenoses. Unfortunately, the restenosis rate is high after CEA. This study aims to demonstrate the predictive role of carotid plaque features and inflammatory biomarkers (monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic inflammatory index (SII), Systemic Inflammation Response Index (SIRI), and Aggregate Index of Systemic Inflammation (AISI)) in carotid restenosis and mortality at 12 months following CEA. METHODS The present study was designed as an observational, analytical, retrospective cohort study and included all patients over 18 years of age with a minimum of 70% carotid stenosis and surgical indications for CEA admitted to the Vascular Surgery Clinic, Emergency County Hospital of Targu Mures, Romania between 2018 and 2021. RESULTS According to our results, the high pre-operative values of inflammatory biomarkers-MLR (OR: 10.37 and OR: 6.11; p < 0.001), NLR (OR: 34.22 and OR: 37.62; p < 0.001), PLR (OR: 12.02 and OR: 16.06; p < 0.001), SII (OR: 18.11 and OR: 31.70; p < 0.001), SIRI (OR: 16.64 and OR: 9.89; p < 0.001), and AISI (OR: 16.80 and OR: 8.24; p < 0.001)-are strong independent factors predicting the risk of 12-month restenosis and mortality following CEA. Moreover, unstable plaque (OR: 2.83, p < 0.001 and OR: 2.40, p = 0.04) and MI (OR: 3.16, p < 0.001 and OR: 2.83, p = 0.005) were independent predictors of all outcomes. Furthermore, AH (OR: 2.30; p = 0.006), AF (OR: 1.74; p = 0.02), tobacco (OR: 2.25; p < 0.001), obesity (OR: 1.90; p = 0.02), and thrombotic plaques (OR: 2.77; p < 0.001) were all independent predictors of restenosis, but not for mortality in all patients. In contrast, antiplatelet (OR: 0.46; p = 0.004), statin (OR: 0.59; p = 0.04), and ezetimibe (OR:0.45; p = 0.03) therapy were protective factors against restenosis, but not for mortality. CONCLUSIONS Our data revealed that higher preoperative inflammatory biomarker values highly predict 12-month restenosis and mortality following CEA. Furthermore, age above 70, unstable plaque, cardiovascular disease, and dyslipidemia were risk factors for all outcomes. Additionally, AH, AF, smoking, and obesity were all independent predictors of restenosis but not of mortality in all patients. Antiplatelet and statin medication, on the other hand, were protective against restenosis but not against mortality.

Abstract
Introduction: Cutaneous squamous cell carcinoma (cSCC) is one of the most frequently occurring types of cancer in humans. Scientometric research is an innovative method for analyzing the research trends in various domains, with great implications in the field of medicine. Materials and Methods: We searched the Web of Science database with the following established query terms: “Squamous cell carcinoma”, “skin”, and “immunohistochemistry”. After applying the inclusion and exclusion criteria, a total of 76 articles were selected. The present study aims to analyze, based on the frequency of use of keywords with scientometric algorithms and map-based distributions, the trends of the research concerning cSCCs in 2017–2022. Results: A graphical representation based on 11 scientometric maps presented the division of the keywords into seven clusters, from which seven categories of research interest were defined. The clusters represent a multidisciplinary approach to the diagnosis and treatment of cSCCs, cancer diagnostics, patient outcomes, histopathological importance, management of cSCCs, role of progression, and adequate treatment of and importance of immunohistochemistry for cSCCs. The distribution of the citations shows the importance of the available research on cSCCs by analyzing the first five most-cited articles included in our study in direct concordance with the seven defined clusters. Conclusion: The scientometric research method reveals the interest of research in the multidisciplinary approach used to obtain the best outcomes for the patient, including a targeted investigation, as well as diagnostic and treatment options. The trends in the research reveal that histopathological diagnostics and immunohistochemistry, combined with molecular techniques, are the most important tools used to establish a personalized diagnosis, thus increasing the quality of life and life expectancy for patients with cSCCs.

Abstract
Intrauterine devices (IUDs) are very common as a method of birth control. By adding progesterone (levonorgestrel), a decrease in the risk of complications has been documented, including the risk of perforation. Even though only a few complications have been described, adjacent organs may be involved in the case of migration—a life-threatening situation. A 45-year-old G4P2 woman was seen in our clinic for LNg-IUD removal, according to the medical instructions. Her main complaints were abdominal discomfort, low back pain, and recurrent menorrhagia. A “lost” IUD was initially suspected; the patient confirmed the detection and removal of the control strings, and a subsequent discussion related to delayed transmural migration of the IUD being followed. The ultrasonography revealed the migration of the IUD to the uterine cervix and size-decreased uterine fibroids, confirming the effectiveness of the LNg-IUD. The MRI and ultrasonography being useless, a subsequent X-ray and CT scan were requested, both confirming a myometrium-positioned IUD, adjacent to the serosa and lumbosacral plexus. Even though the IUD is considered a safe device with reversible effect, it can be associated with severe morbidity, with an ultrasound follow-up being required. For more precise detection of the IUD, we strongly recommend an X-ray or CT scan examination, followed by safe removal.

Abstract
Thrombocytopenic purpura (TTP) is a rare, potentially fatal pathology characterized by microangiopathic thrombotic syndrome and caused by an acute protease deficiency of von Willebrand factor, ADAMTS13. Moreover, ADAMTS13 deficiency promotes microthrombosis led by the persistence of ultra-large VWF multimers in the blood circulation. According to the few studies involving pregnant participants, the heterogeneity of manifestations has made this pathology difficult to diagnose, with an unexpected occurrence and increased risk of maternal and fetal morbidity and mortality. We reported on the case of a 28-year-old pregnant woman with an obstetric score of G2P0 who presented to the obstetrics and gynecology department of our clinic with the complaint of minimal vaginal bleeding. The evolution of our case was severe and life-threatening, a “race against the clock”, with our goal being to emphasize the importance and difficulty of diagnosing TTP in the absence of specific symptomatology. We faced a lack of technological support for a correct and complete diagnosis, and the first manifestation of this disease was the intrauterine death of the fetus. After completing all the necessary procedures, the placental tissue was sent for further histopathological evaluation. We highlighted the importance of monitoring ADAMTS13 for relapses monthly, with prophylaxis being essential for maternal and fetal mortality and morbidity.

Abstract
Background and Objectives: Basal carcinoma of the skin (BCC) is part of the nonmelanoma skin cancer (NMSC) family and is the most frequently occurring type of skin cancer in humans. A combination of clinical and histopathological approaches is necessary in order to establish the best treatment regime for patients who have been diagnosed with this type of cancer. The objective of the present study was to establish the statistical value of prediction for certain sociodemographic characteristics (age category and environment of origin) and histopathological parameters of the subjects that could be related to the incidence of diagnosis with certain histopathological subtypes of BCC. Materials and Methods: In order to verify the veracity of the established research hypotheses, we conducted a retrospective study based on the histopathological reports of 216 patients who were treated at the Pathology Department of Mureș Clinical County Hospital. Results: Cystic BCC is higher in patients who are older than 71 years of age, and the superficial multicentric and keratotic subtypes are more frequently diagnosed in urban areas. Patients who have been diagnosed with the superficial multicentric BCC subtype are not usually very old in contrast to the patients who tend to be diagnosed with the cystic BCC subtype. The nodular BCC subtype is positively associated with ulceration (p = 0.004); the superficial multicentric BCC subtype is positively associated with intra- and peritumoral inflammatory infiltrate (p = 0.022, p = 0.034) and negatively associated with ulceration (r = -0.218, p = 0.001). The infiltrative BCC subtype is positively associated with ulceration (p = 0.021), and the keratotic BCC subtype is positively associated with peritumoral inflammatory infiltrate (p = 0.02). Conclusions: Depending on each patient's epidemiological and sociodemographic data, a pattern can be established regarding the appropriate clinical and treatment approaches for that patient, which can be supported based on the implications of the histopathological diagnostic. This can lead to an improvement in the patient's quality of life and increased satisfaction with the provided medical services.

Abstract
Introduction: Neuroendocrine neoplasms (NENs) are a heterogeneous group of tumors arising from cells that are part of the diffuse neuroendocrine system. Patients,Materials and Methods: We conducted a retrospective study in which we included a number of 91 cases diagnosed with neuroendocrine tumors (NETs). Descriptive statistics was performed: number of cases based on location, distribution by gender (male/female), distribution by age, and we also performed a morphological and immunohistochemical (IHC) study. Results: The highest number of cases was found in lungs (60 cases). Tumors located on the skin, breast or bladder have been discovered, locations considered rare for this type of tumor. Of all cases diagnosed in the lungs, 59 were diagnosed as small cell carcinomas (SCCs) and only one case as NET. All surgical specimens were positive for chromogranin A (CgA), with a different expression for the other immunomarkers. For the lung biopsies, the most frequently IHC staining was CgA and cluster of differentiation 56 (CD56), with an increased positivity for the latter. Conclusions: CgA remains the most sensitive immunomarker in the diagnosis of NETs. CD56 is the most widely used immunomarker for diagnosing small cell lung tumors. Positive expression of thyroid transcription factor 1 (TTF1) immunomarker does not confirm pulmonary origin of SCCs.

Abstract
Metastatic melanoma is a fatal disease with poor prognosis. Ever since targeted therapy against oncogenic BRAF was approved, molecular profiling has become an integral part of the management of such patients. While molecular testing is not available in all pathology laboratories, immunohistochemistry (IHC) is a reliable screening option. The major objective of the present study was to evaluate whether IHC detection of BRAF and the tumor (suppressor) protein 53 gene (TP53) are reliable surrogates for mutation detection. Formalin-fixed paraffin-embedded samples of melanomas for which molecular data were previously obtained by targeted next-generation sequencing (NGS) between January 2014 and February 2019 were immunostained with BRAF V600E and p53 antibodies. A blinded evaluation of the IHC slides was performed by two pathologists in order to evaluate inter-observer concordance (discordant cases were reviewed by a third observer). The associations between the results of IHC and molecular profiling were evaluated. The study included a series of 37 cases of which 15 harbored a BRAF mutation and five a TP53 mutation. IHC had an overall diagnostic accuracy of 93.9% for BRAF V600E and 68.8% for TP53 compared to NGS. A statistically significant association between the two diagnostic methods was obtained for BRAF V600E (P=0.0004) but not for p53 (P=0.3098) IHC. The κ coefficient for IHC assessment of p53 was 0.55 and that for BRAF V600E was 0.72. In conclusion, the present results evidenced that IHC staining is a reliable surrogate for NGS in identifying the BRAF V600E mutation, which may become an efficient screening tool. Aberrant expression of p53 on IHC is at times associated with TP53 mutations but it was not possible to establish a direct link.

Abstract
BACKGROUND/AIM Chloride intracellular channel protein 1 (CLIC1) activates inflammasomes in rheumatoid (RA) and psoriatic (PsA) arthritis. We studied CLIC1 expression in RA and PsA patients' skin with vasculitis and its variability depending on the therapy used. MATERIALS AND METHODS CLIC1 immunoexpression was evaluated in the vascular (CLIC1-V) and stromal (CLIC1-S) compartments of the RA and PsA skin biopsies of patients treated with methotrexate (MTX), leflunomid (LFN), corticotherapy (CT), or biological therapies. RESULTS MTX significantly reduced CLIC1-S expression (p=0.016), whereas LFN decreased CLIC1-V (p<0.001). LFN therapy duration also correlated with CLIC1-V (p<0.001). CT decreased CLIC1-S expression (p=0.006). CLIC1-S expression persisted in skin biopsies despite of erythrocyte sedimentation rate (ESR, p=0.018) and C reactive protein (CRP, p=0.0026) normalisation. For PsA, CLIC1-S expression significantly related to MTX (p<0.022). Both CLIC1-S (p<0.001) and CLIC1-V (p=0.007) decreased by biological therapies in RA. CONCLUSION CLIC1 expression is strongly influenced by the therapy used. Our data strongly support the extensive evaluation of CLIC1 in RA as a potential marker of inflammation and tool to predict therapy response.

Abstract
Introduction: Neoplasms with pagetoid features are a category of rare lesions defined by the presence of atypical cells at different levels of the epidermis. The most important diseases within this category are mammary Paget disease (MPD), extramammary Paget disease (EMPD), Bowen’s disease, in situ melanoma, and pagetoid reticulosis. Aim: The aim of this analysis was to describe the importance of the cytokeratin 8/18 (CK 8/18) immunostaining in diagnosing MPD and EMPD and differentiating them from other lesions. Materials and Methods: A retrospective study was employed, based on the histopathological and immunohistochemical (IHC) characteristics of 30 cases that presented pagetoid features. The cases were processed and analyzed at the Department of Pathology, Mureş Clinical County Hospital, Târgu Mureş, Romania, from 2017 to 2020. Results: Five MPD cases, one EMPD case, one pagetoid reticulosis case, 10 Bowen’s disease cases, and 13 in situ melanoma cases were collected. Under Hematoxylin–Eosin staining, cells presented pale cytoplasm in MPD, EMPD, and in 25% of the melanoma cases. Hyperchromasia with nuclear enlargement was seen in all cases. Immunostaining with CK 8/18 was positive in all MPD and EMPD cases. Tests for CK7, p63, and CK AE1/AE3 were positive in MPD, EMPD, and Bowen’s cases. Tests for S100, SRY-box transcription factor 10 (SOX10), human melanoma black 45 (HMB45), and Melan A were positive in melanoma cases, while cluster of differentiation (CD)3, CD4, and CD8 tests were positive in the pagetoid reticulosis case. Conclusions: CK 8/18 is an IHC marker that can help establish the diagnosis of MPD and EMPD and differentiate them from other pagetoid neoplasms, ensuring the proper diagnosis and prognosis are provided.

Abstract
Abstract
Acute myocardial infarction (AMI) is a disease associated with high morbidity and mortality. Currently there are no available treatments specifically targeting the post-ischemic myocardial processes that lead to heart failure and recurrent coronary events. The innate immune system plays a central role in the two consecutive phases that follow an acute ischemic event: the inflammatory phase and the reparatory phase. The inflamatory phase involves a massive infiltration of neutrophils and inflammatory Ly6Chi monocytes into the injured myocardium. The reparatory phase is orchestrated by reparatory Ly6Clo macrophages that clear necrotic and apoptotic cells through efferocytosis, secrete anti-inflammatory mediators and stimulate fibrosis and repair. Important recent studies provided proof that Ly6Chi monocytes that enter the myocardium in the inflammatory phase upregulate the orphan nuclear receptor Nr4a1 and switch phenotype to Ly6CloNr4a1hi reparatory macrophages. Additionally, neutrophils have been shown to promote cardiac recovery by upregulating expression of the efferocytosis receptor MerTK on reparatory macrophages. A finely tuned balance between the inflammatory and the reparatory phases is thus essential for limiting myocardial damage and promoting efficient recovery. Treatment strategies targeting only the inflammatory phase have so far failed to improve prognosis in AMI patients. A detailed understanding of the interplay between the two phases of the innate immune response is paramount for designing efficient therapies able to improve post- AMI prognosis. In the current review, we summarize the state-of-the-art of the field and discuss previous therapeutic attempts and currently ongoing clinical trials targeting innate immune mechanisms in AMI patients.

Abstract
OBJECTIVE The objective of this study is to evaluate if the immunohistochemical expression of a pulmonary apoptosis marker and plasma level of Fas ligand (FasL) correlates with the dose- and time-dependent severity of lung injury, induced by the administration of lipo-polysaccharide (LPS) in an endotoxemic rat model. MATERIALS AND METHODS Our study included 30 male Wistar rats, randomly divided into three groups: one control group (n=6) and two experimental groups (n=12÷group), in whom we induced endotoxemia by intraperitoneal injection of progressively increasing doses of LPS (5, 10 mg÷kg). We measured FasL plasma levels of the rats at different time points and analyzed the relationships with markers of lung injury. To investigate the level of caspase 3-protein expression, the immunohistochemistry of the lung tissue was assessed. RESULTS The median percentage of caspase 3-stained cells for the 5 mg÷kg LPS dose was 0.36%, for the 10 mg÷kg LPS dose was 0.4% and for the control group was 0.03% (p<0.0001). The elevated expression levels of caspase 3 were consistent with the altered lung morphologies observed (rs=0.88). LPS administration in rats resulted in a significant dose-dependent increase in the levels of plasma FasL (p<0.0001). These levels correlated with markers of lung injury: degree of hypoxemia (rs=-0.42), histological measured lung injury score (rs=0.72), the density of the caspase 3 staining cells in the immunohistochemistry assessment of apoptosis (rs=0.81) and with the plasma RAGE (receptor for advanced glycated end-products) values (rs=0.70). CONCLUSIONS Apoptosis is increased in edotoxemia induced lung injury and is likely to contribute to alveolar injury.

Abstract
Granulomatous inflammations are a particular type of chronic septic or aseptic inflammation, in which infectious or non-infectious agents are difficult to eliminate by the immune system. These are type IV hypersensitivity reactions mediated by pre-sensitized T-lymphocytes cells CD4+ and CD8+ lymphocytes. Disorders included in this category are: tuberculosis, leprosy, syphilis, sarcoidosis, type I diabetes, multiple sclerosis, Crohn's disease and rheumatoid arthritis. At cutaneous level, this pattern of granulomatous reaction is characterized by a chronic inflammation with formation of granulomas consisting of a variable number of histiocytes, multinucleated giant cells and lymphocytes. Granulomatous dermatoses should be differentiated from other primary or secondary lesions affecting the skin such as inflammation or tumors. Often granulomatous dermatoses can be confused with other skin disorders, both clinically and histological. Histopathology examination can add important information and clarify the diagnosis. This paper presents a series of three clinical cases of granulomatous skin occurring in the elderly patients confirmed at histology examination. Clinical and histology criteria were analyzed, along with specific differential diagnosis, based on data from the literature.

Abstract
Cutaneous piloleiomyoma, angioleiomyoma and genital leiomyoma are variants of superficial cutaneous leiomyoma. The main purpose of this paper was to present clinical, histopathological and immunohistochemical diagnosis criteria for an unusual case of pilar leiomyoma in an 18-year-old male patient. The initial clinical aspect was very similar to spontaneous eruptive keloids: red-violet color, painless, aspect of "crab pincers" of some of the lesions, epidermis atrophy, telangiectasia, located on acneiform zones and compliance with cephalic extremity. The patient had no history of trauma, surgery or acne. Local treatment of one lesion was performed with cryotherapy using liquid nitrogen (-172°C) together with intra-lesion steroid injections, occlusive dressings and silicone gel. Local therapy did not showed notable results, moreover the lesion become painful. Skin biopsy with histological and immunohistochemical analysis revealed the diagnosis of multiple cutaneous pilar leiomyoma without atypia. The particularity of the case stands in the atypical onset followed by explosive increasing of lesions number and the appearance of pathognomonic pain after local therapy.

Abstract
Abstract
Background: We hypothesized that an ideal heart valve replacement would be acellular valve root scaffolds seeded with autologous stem cells. To test this hypothesis, we prepared porcine acellular pulmonary valves, seeded them with autologous adipose derived stem cells (ADSCs) and implanted them in sheep and compared them to acellular valves.
Methods: Fresh porcine pulmonary valve roots were decellularized with detergents and enzymes. ADSCs were isolated from subdermal fat and injected within the acellular cusps. Valves were then implanted in an extra-anatomic pulmonary position as RV to PA shunts: Group A (n=6) consisted of acellular valves and Group B (n=6) of autologous stem cell-seeded acellular xenografts. Sheep were followed up for 6 months by echocardiography and histologic analysis was performed on explanted valves.
Results: Early evolution was favorable for both groups. All Group A animals had physiologic growth without any signs of heart failure and leaflets were found with preserved structure and mobility, lacking signs of thrombi, inflammation or calcification. Group B sheep however expressed signs of right ventricle failure starting at one month, accompanied by progressive regurgitation and right ventricle dilatation, and the leaflets were found covered with host tissue. No cells were found in any Group A or B explants.
Conclusions: Acellular stabilized xenogeneic pulmonary valves are reliable, stable, non-immunogenic, non-thrombogenic and non-calcifying scaffolds with excellent hemodynamics. Seeding these scaffolds with autologous ADSCs was not conducive to tissue regeneration. Studies aimed at understanding these novel observations and further harnessing the potential of stem cells are ongoing.

Abstract
The fascia's and subcutaneous adipose tissue's impairment by mono or polymicrobial infection, which also can involve the skin and the muscles, is rarely seen in oro-maxillo-facial area. The present case report is presenting a case of necrotizing fasciitis in a patient who had a history of an invasive squamous cell carcinoma of the soft palate, with surgical treatment and with radiotherapy. He was admitted in our Clinic with malaise and subsequently developed a toxico-septic shock. Clinical symptoms, serological and bacteriological analysis and histopathological examination confirmed the diagnosis of necrotizing fasciitis (NF). The patient subsequently underwent a series of surgical reconstruction and aesthetic treatments because of the complications that had arised in the meantime. Postoperative evolution was favorable towards complete closure of the defect. The prognosis of this disease is generally reserved, the favorable evolution depending on the possibility of wound sterilization and the surgery is required despite its mutilating effect.

Abstract
Different animal models of experimental lung injury have been used to investigate mechanisms of lung injury. Lipopolysaccharide (LPS) administration is the most often used approach to model the consequences of bacterial sepsis. We created an endotoxemia rat model, simulating sepsis-related lung injury, in order to quantify the time and dose dependent severity lesions induced by the administration of lipopolysaccharide. Our study included 42 male Wistar rats, randomly divided into four groups: one control group (n=6) and three experimental groups (n=12/group) in whom we induced sepsis by intraperitoneal injection of progressively increasing doses of LPS (3, 5, 10 mg/kg). At six hours, the animals included in the groups with higher doses of LPS developed thrombocytopenia, elevated lactate levels, and liver and renal injury in a dose and time dependent manner. The severity of hypoxemia at six hours correlated with the increasing doses of LPS, with a slight improvement at 24 hours. Lung injury scores became more severe with increased dose and time of exposure to LPS without reaching the level of hyaline membranes formation. We also demonstrated translocation of a protein from the airspaces into plasma (RAGE - receptor for advanced glycation end products). Induction of sepsis using LPS is a known experimental model, but LPS treatment in rats does not cause the severe endothelial and epithelial injury that occurs in humans with acute respiratory distress syndrome (ARDS). In our study, the clinical, laboratory and histopathological findings confirmed sepsis and the damage of the alveolar-capillary membrane in a dose-dependent manner.

Abstract
Quantification of local ischemia and inflammatory response syndrome correlated with histological changes associated with ischemia-reperfusion injury (IRI) after revascularization techniques. We included 12 adult male Wistar rats, aged eight weeks that were randomly divided into two groups. The first group acted as the control and at the second group, we induced diabetes by intraperitoneal streptozotocin administration (60 mg/kg). After eight weeks, the rats were subject to ischemic preconditioning for 10 minutes at three regular intervals. Twenty-four hours post-preconditioning, both groups were subject to ischemia for 20 minutes, followed by 30 minutes of reperfusion. Oxygen extraction was higher in Group 1, the arterio-venous CO2 gradient was higher in the control group, but not significant. The lactate production was higher in Group 1. The second group had a higher Na+ and also a significant difference in K+ values. Receptor for Advanced Glycation End (RAGE) values were higher in the second group but with no significant difference (RAGE1=0.32 ng/mL versus RAGE2=0.40 ng/mL). The muscle samples from the control group displayed significant rhabdomyolysis, damage to the nucleus, while the preconditioned group showed almost normal morphological characteristics. The lungs and kidneys were most damaged in the control group, with damage expressed as thickened alveolar septa, neutrophil infiltrates, eosinophilic precipitates in the proximal convolute tubule. Ischemic preconditioning significantly attenuates the ischemic reperfusion injury.

Abstract
Oral cancer was ranked as the sixth worldwide most common cancer, but recent studies noticed an overall downward trend in its incidence. However, for tumors localized on the tongue, the incidence seems to increase. The malignant transformation of many carcinomas is associated with loss of epithelial differentiation and gain of a mesenchymal phenotype, a process known as epithelial-mesenchymal transition (EMT) which for oral squamous cell carcinomas (OSCC) could be a predictor and a prognostic factor. The aim of our study was to investigate immunohistochemically the E-cadherin/N-cadherin "switch" and vimentin expression as markers of EMT process in tongue OSCC. Thus, we analyzed 15 cases of tongue OSCC by enzymatic double immunohistochemistry using the following double pairs of antibodies: E-cadherin/vimentin and N-cadherin/E-cadherin. E-cadherin reactivity was recorded in all the investigated cases, the pattern of expression being both membranous and cytoplasmic, with the membrane pattern decreasing simultaneously with the decrease of the differentiation degree and with the increase of invasion phenotype, while the cytoplasmic pattern had an opposite behavior. Tumor parenchyma reactivity for vimentin was noticed in 73.3% and its expression was more obvious in tumor cells from the periphery of proliferative islands and in acantholytic carcinomatous cells. N-cadherin reactivity was restricted to only 33.33% of the investigated cases and its expression was prevalent in poorly differentiated forms. In conclusion, in tongue squamous cell carcinomas at the invasion front the E-cadherin reactivity decreases while vimentin expression increases, with a cytoplasmic N-cadherin reactivity in a few of the observed cases. This EMT phenotype was correlated with the decrease of differentiation degree, with the increase of the type of invasion pattern and with increasing disease' stages and thus these EMT markers could be used for prognostic stratification of such patients.

Abstract
Aneurysmal dermatofibroma (AD) or aneurysmal fibrous histiocytoma (AFH) is a relatively rare form of histiocytoma representing less than 2% of total cases. It shares many clinical and dermoscopic similarities with skin tumors, especially malignant melanoma and Kaposi's sarcoma, which can make differentiation problematic. We report the case of a 53-year-old man, who presents with a black nodular tumor with increased consistency, edges infiltrated from the surface to depth, spontaneous and sensitive to touch that shows rapid growth in the last three months. Dermoscopically, the central region consists of intricate areas colored in red, violet, blue-white and black. On the periphery stand two rings, centrally white and peripherally pigmented, with an abundance of polymorphic capillaries. To clarify the diagnosis, the lesion was widely excised and histopathological examination was performed, which revealed immunophenotypical tumor cells negative for HMB-45 and S100, and numerous CD68 macrophages between tumor cells. This aneurysmal fibrous histiocytoma shows both clinical and dermoscopically discrete differential criteria, which are not specific and that make it difficult to distinguish from malignant melanoma and Kaposi's sarcoma, and required performing histopathology and immunohistochemistry.

Abstract
Although, generally BCC growths slowly and is minimally invasive, tumors developed in the head and neck region behave more aggressively with deep tissue invasion, recurrence and even local or distant metastases, causing significant morbidity or mortality. Recently, numerous studies have been conducted in order to identify new prognostic markers of BCC aggressiveness, but the results are not consistent. Thus, we were interested here in the immunohistochemical investigation of p53, D2-40 and α-SMA expression in the aggressive forms (eight infiltrative-morpheaform, six micronodular and six metatypical cases) versus superficial facial BCCs (five cases). As results, we first noticed that p53, D2-40 and α-SMA expression varied between different types of investigated BCCs. The highest reactivity was observed in metatypical subtype for the D2-40. p53 was mainly expressed in the micronodular BCC subtype and on overall, the tumor reactivity to this marker correlated directly with the reactivity for the other two used biomarkers. The infiltrative-morpheaform facial BCCs were peculiar more reactive to α-SMA. For all three investigated markers, regardless the histological subtype, the tumor reactivity was higher at the advancing edge, and in addition, at this level we noticed a D2-40 and α-SMA stromal reactivity for some cases of the more aggressive BCC subtype (peculiar in metatypical subtype). Thus, we concluded that in order to identify the most aggressive forms of facial BCCs it is useful to investigate these three markers, and this is even more important as they can all constitute therapeutic targets.

Abstract
According to the definition of WHO, pagetoid reticulosis (PR) is characterized by the presence of unique skin lesion in the shape of patches or plaques caused by the proliferation of atypical T-cells in epidermis. We report the case of a 50-year-old female, presenting a 50×65 mm erythematous scaly patch, well-defined, slightly infiltrated, discrete polycyclic, on the right buttock, which appeared and developed in about 6-8 months. The clinical and dermatoscopic aspects suggested a Bowen's disease. A skin biopsy was performed. The histological examination of the pieces confirmed the presence of monoclonal lymphoid infiltrate with obvious phenomena of epidermotropism. Immuno-phenotypically the tumoral cells express intensively CD3 and CD8 and focally CD4. Surgical excision was performed without radiotherapy and chemotherapy. The patient was followed-up for 42 months without local relapses, distant lymph nodes or visceral metastases. Microscopic aspect of the lesion corresponds to stage I-II of mycosis fungoides (MF) (patches or plaques); the diagnosis was PR Woringer-Kolopp type. The most recent classification of skin lymphomas (WHO, 2008) confirms that the immunohistochemical profile of T-cells can be CD4+ and CD8- or CD4- and CD8+, and frequently CD30+, in contrast to the classical versions of MF. Pagetoid reticulosis type Woringer-Kolopp, a rare particular variant of mycosis fungoides, is suspected in cases with unique, distinctive lesion and confirmed only by histological immunohistochemistry. Treatment consists of surgical excision of the lesion with long follow-up.

Abstract
UNLABELLED Dermatofibrosarcoma protuberans (DFSP), a rare type of mesenchymal neoplasm, is defined by the WHO as a superficial sarcoma with low-grade malignancy that develops in the cutaneous and subcutaneous tissues. The purpose of this paper is to present a case of a giant DFSP, with post-traumatic onset in childhood and a very long evolution. CLINICAL DATA 51-year-old Caucasian patient presents for 41 years a presternal neoplastic lesion, with onset at 10-year-old, few months after a strong trauma. The patient addressed for a clinic examination, secondary to a spontaneous hemorrhage of the lesion. The local examination reveals the presence of a red-purple polynodular neoplastic lesion of 180×110×30 mm, of firm consistency, adherent to the subcutaneous tissue, painless, with lateral extension at 8 o'clock as an erythematous infiltrated atrophic plaque appearance. One of these nodular masses presents surface ulceration and areas of necrosis. The CT scan did not detect any infiltration into the pectoral muscle or loco-regional metastasis. Under general anesthesia a wide surgical excision with free macroscopic margins of 3 cm was performed. Histopathological diagnosis was DFSP, with evidence of tumoral spindle cells disposed in storiform pattern, embedding small adipocyte panicles, creating a lace-like or honeycomb appearance. Immunohistochemically, the tumor cells express an intense and diffuse CD34 and they are negative for S-100 and SMA. The Ki-67 is focal positive in almost 2-4%. Clinical and paraclinical monitoring at 18 months follow-up does not detect any local recurrences or metastases, and an excellent quality of life.

Abstract
Squamous cell carcinoma is defined as an invasive epithelial neoplasm, with variable degrees of squamous differentiation, with or without keratinization. It is origins stand at the level of the keratinized stratified squamous epithelium (skin) or non-keratinized (oral mucosa, esophageal mucosa, uterine exocervical mucosa), but it can also be found in squamous metaplasia areas (uterine endocervix or trachea-bronchial tree). This report presents the case of an oral squamous cell carcinoma as a second malignancy in the same anatomical territory, in a patient with prior treatment for chondrosarcoma, both surgical and radiotherapy. The tumor had appeared 5-6 months prior and had undergone a relatively rapid growth, this being the patient's main motive for addressing the doctors. The tumor was greyish, with imprecisely demarcated margins, of firm consistency, bleeding and with local necrotic deposits. The tumor extended from the incisive region to the maxillary tuberosity, towards the cheek mucosa and the soft palate. After a large excision, the histopathological diagnosis was infiltrative keratinizing squamous cell carcinoma, with moderate differentiation, with origins in the oral mucosa, infiltrating the whole of the maxilla and the maxillary sinus mucosa. Approximately three months after the surgery, a new tumor appeared in the oral cavity, on superior and inferior mucosa of the right cheek, extending towards the right buccal commissure, implying a relapse of the primary tumor. Postoperative oncological therapy included standard chemotherapy, which resulted in favorable postoperative evolution. This case is interesting by the association, of two metachronous malignant tumors, of different histological origin: a chondrosarcoma and a squamous cell carcinoma, at an interval of 25 years.

Abstract
BACKGROUND Helicobacter pylori infection is an important cause of gastritis in childhood, its role in the pathogenesis of peptic ulcer disease in adults and children being generally known. In some cases, there are therapeutic management issues, because they do not heal or they often relapse, although treatment regimens are applied as recommended. Our aim was to analyze the relationship between endoscopic appearance and histological changes of the gastric mucosa in children with gastritis associated with H. pylori infection, in which persistent infection after treatment was found. MATERIALS AND METHODS It was a prospective study on 1332 children assessed in our Service (Ist Pediatric Clinic, Tirgu Mures, Romania), between January 2008 and January 2013, for gastritis with various etiologies. There were 609 cases of gastritis-associated with H. pylori infection. RESULTS The average age of patients was 13.21 years; the higher incidence was noted in 13-18-year-old group, female gender and rural areas provenience; a number of 544 patients diagnosed with gastritis with H. pylori were reassessed subsequently; after treatment, gastritis has healed and the infection was eradicated in 88.23% cases after a month, while in 64 patients infection persisted. After a second regimen, endoscopic-histological modifications persisted in 31 (5.69%) cases; 1.28% cases remained positive for longer. CONCLUSIONS H. pylori infection was associated with high age group, as well as with endoscopic modifications; also, the presence of H. pylori was correlated with histopathologic diagnostic. We try to emphasize the importance of assessing bacterial resistance to antibiotics, studying of bacterial genome and genetic susceptibility of human subjects.

Abstract
PURPOSE To evaluate the correlations between the pro-inflammatory interleukins IL-6 and IL-8 and the anthropometric measurements in malnourished vs. non-malnourished children. PATIENTS AND METHODS We have examined 219 children from Pediatric Clinic I, University of Medicine and Pharmacy of Tirgu Mures, Romania, during January 1, 2012-March 1, 2013 and divided according to Body Mass Index (BMI kg/m(2)) in the following two groups: 164 with normal nutritional status - control group (BMI between -2SD and +2SD), and 55 children with malnutrition (BMI <-2SD). All the children were evaluated anthropometric: BMI, weight for age (W/A), height for age (H/A), mid-upper-arm circumference (MUAC), tricipital skinfold (TSF) and paraclinical: IL-6 and IL-8 levels. RESULTS From 219 children, 25.1% were malnourished. The mean age was 5.16 years in malnourished. IL-6 and IL-8 mean levels were 2.54 pg/mL, respectively 6.83 pg/mL in malnourished and 6.02 pg/mL, respectively 9.06 pg/mL in non-malnourished. By statistically comparing IL-6 in malnourished group vs. control group, we observed decreased values (p<0.0001) and also significantly lower values for IL-8. We also obtained statistical differences between the two groups in BMI, W/A, MUAC and TSF. The BMI SD have an increasing trend line, from -4SD in newborn malnourished to -2SD in near 18-year-old malnourished; the trend line had only a slight ascension in non-malnourished children. CONCLUSIONS The interleukin levels and BMI, W/A, MUAC and TSF are significantly lower in malnourished children than in non-malnourished. This functional impairment may be involved in the malnutrition to develop a specific immune response in these children.

Abstract
Acinic cell carcinoma (ACC) is the third most common epithelial malignancy of the salivary glands in adults, exhibiting a low-grade malignancy that mainly occurs in the parotid gland and at a relatively younger age than other salivary gland tumors. We performed an immunohistochemically study regarding angiogenesis in ACC, by assessing the CD105+ tumor microvessels density and investigating the VEGF and its receptors VEGFR1 and VEGFR2 expression in tumor samples. The results indicated an active angiogenesis in ACC, with the highest CD105-MVD score recorded in the solid variant. This fact was supported by the reactivity of tumor cells and endothelial blood vessel cells for VEGF and its receptors (VEGFR1 and VEGFR2). Thus, we concluded that in ACC do exist autocrine and paracrine VEGF loops implicated in growth and progression of this kind of salivary gland tumors.

Abstract
Basal cell carcinoma (BCC) is one of the most common skin neoplasms in humans, accounting for almost 80% of all non-melanoma skin cancers worldwide. The nodular and infiltrative-morpheaform are the most common BCC types in the head and neck region and together with the micronodular subtypes are the most aggressive tumors, because of their tendency to infiltrate the deep subcutis, muscles and even bones. To explain the local aggressive behavior and their metastatic potential, many studies have been performed to identify the molecular determinants implicated in BCC tumor progression. For this reason, we investigated the immunohistochemical expression of CXCR4, MMP-13 and β-catenin expression in six metatypical, eight infiltrative-morpheaform, six micronodular and five superficial facial BCCs. For all three markers, the tumor reactivity varied with the histological type. The highest reactivity was observed in metatypical subtype, especially at the level of areas with squamous cells differentiation. The lowest reactivity was recorded in micronodular and superficial BCC subtypes. Regardless histological subtype, the tumor reactivity was higher at the advancing edge and additional a strong stromal reaction was noticed for all investigated markers peculiar in fibroblasts, inflammatory cells and endothelial cells. All these data proved the utility of CXCR4, MMP-13 and β-catenin immunohistochemical investigation in BCCs both for identification of high-aggressive tumors and to develop novel more efficient therapeutic strategy for these patients by targeting these biomarkers.

Abstract
Cutaneous metastases from signet ring cell gastric carcinoma are uncommon. A 35-year-old male presented with a three-month history of multiple asymptomatic, indurated, pinky colored nodules of 2.5 to 4 cm in diameter, without any local and general symptoms. Nodule biopsy revealed an infiltrating signet ring cell carcinoma. Gastroscopy and biopsy confirmed the diagnosis of gastric carcinoma with signet ring cells. The present report describes an unusual clinical case of a young patient diagnosed with cutaneous metastasis before detection of his gastric carcinoma.

Abstract
Chronic Obstructive Pulmonary Disease (COPD) is one of the leading causes of morbidity and mortality in the industrialized and in the developing countries. It is believe, at least in part, that some of the structural changes that occur in COPD would be a result of epidermal growth factors (EGFs) and their receptors. Therefore, our study aims was to examine the expression patterns of EGF and their receptors (EGFR1 and c-erbB2) in the bronchial mucosa from the biopsy specimens harvested from smoking and non-smoking CB patients, compared with their expression in normal controls. The statistical analysis proved that for both EGF and EGFR1 reactivity were significant correlation with smoking status and FEV1% scores. Thus, we found that the highest levels of its expression were recorded in smoker CB patients with higher FEV1% scores. Regarding cellular localization and staining pattern, we noticed a cytoplasmic and nuclear immunostaining for EGF in bronchial epithelium both for control and CB subjects at the level of basal and ciliated cells. For the receptors, reactions were at the membrane level especially at the lower lateral junctions between ciliated cells and their junctions with basal cells. This reactivity proved the pathogenic implication of the EGF and their receptors in patients with CB and suggests that blockade of the EGFR pathway can be an alternative successful therapy.

Abstract
BACKGROUND Chronic rejection (CR) also called cardiac allograft vasculopathy (CAV) is, besides infections and malignant tumors, the leading cause of death during the late period of post-heart transplant. PATIENTS AND METHODS In this paper, we present a series of seven cases with chronic post-transplant cardiac rejection in the light of our experience related to histopathological aspects, difficulties in diagnosing and survival time. RESULTS Our study comprises patients whose ages ranked at the time of transplant between 33 and 58 years, with a mean age of 47.71 years, the ratio between men and women being 6:1. Chronic rejection - cardiac allograft vasculopathy occurred in all seven patients comprised in this study, the earliest in the second year post-transplant (three patients), followed by the third year (one patient), the seventh and eighth year (one patient) and the latest survival period being over 11 years (one patient). Four out of the seven patients with chronic rejection events were preceded by episodes of acute cellular rejection. The most convincing indirect evidence of chronic rejection in endomyocardial biopsies were: ischemic events of the myocardiocytes and impaired microvascular network because of perivascular and interstitial fibrosis. CONCLUSIONS Our study shows that the most important morphological factors correlated with the manifestation of chronic rejection were the episodes of acute cellular rejection or perivascular and interstitial fibrosis, these injuries also being indirect signs mainly detectable at the level of endomyocardial biopsies.

Abstract
Kaposi sarcoma is a low-grade neoplasm first described by Moricz Kaposi in 1872. Although many attempts have been made to explain its pathogenesis, its etiology still remains obscure. In this regard, many aspects of the disease's genetic, epidemiological and histopathological backgrounds are even today unclear. We present the case of a 57-year-old male patient, constant HIV negative, with a history of plaque-like lesions on his right foot approximately two years ago. Following surgical removal, a diagnosis of Kaposi sarcoma, plaque stage was settled. One year after, the patient was admitted to the hospital for pain in the right ankle and foot, associated to paresthesis and trophic lesions at this level. Similar lesions developed in the popliteal fossa. Biopsy and subsequent histological and immunohistochemical examination revealed a KS at that level. The most recent hospital admission revealed the appearance of an indolent lymphadenopathy in the groin. Our case represents a rare occurrence of Kaposi sarcoma at a HIV-negative patient, which, after several local recurrences and progressive behavior, produced a lymph node involvement at the groin level. The immunohistochemical assessments have confirmed the diagnosis.
