Abstract
Thick cutaneous melanomas (Breslow depth > 4 mm) are locally advanced tumors, generally associated with poor prognosis. Nevertheless, these tumors sometimes display unpredictable behavior. This study aims to analyze clinical and histopathological features that can influence the prognosis of thick melanomas. This is a retrospective study on 94 thick primary cutaneous melanomas diagnosed between 2012 and 2018 that were followed-up for at least five years to assess disease progression and survival. We evaluated the age, gender, tumor location, histological subtype, Breslow depth, Clark level, resection margins, mitotic index, the presence/absence of ulceration, necrosis, regression, microsatellites, neurotropism, lymphovascular invasion, and the pattern of tumor-infiltrating lymphocytes, and their association with disease progression and survival. By conducting univariate analysis, we found that progression-free survival (PFS) was significantly associated with female gender, the superficial spreading melanoma (SSM) subtype, mitotic index, necrosis, microsatellites, and perineural invasion. Overall survival (OS) was significantly associated with female gender, Breslow depth, SSM subtype, necrosis, microsatellites, and perineural invasion. Through multivariate Cox proportional hazards regression, we found that the only factors associated with PFS were Breslow depth, necrosis, microsatellites, and perineural invasion, while the factors associated with OS were Breslow depth, necrosis, microsatellites, and perineural invasion. Certain histopathological features such as Breslow depth, necrosis, microsatellites, and perineural invasion could explain differences in disease evolution. This is one of the first studies to demonstrate an association between necrosis and perineural invasion and outcomes in patients with thick melanomas. By identifying high-risk patients, personalized therapy can be provided for improved prognosis.

Abstract
Breast cancer represents a paramount global health challenge, warranting intensified exploration of the molecular underpinnings influencing its progression to facilitate the development of precise diagnostic instruments and customized therapeutic regimens. Historically, the Golgi apparatus has been acknowledged for its primary role in protein sorting and trafficking within cellular contexts. However, recent findings suggest a potential link between modifications in Golgi apparatus function and organization and the pathogenesis of breast cancer. This review delivers an exhaustive analysis of this correlation. Specifically, we examine the consequences of disrupted protein glycosylation, compromised protein transport, and inappropriate oncoprotein processing on breast cancer cell dynamics. Furthermore, we delve into the impacts of Golgi-mediated secretory routes on the release of pro-tumorigenic factors during the course of breast cancer evolution. Elucidating the nuanced interplay between the Golgi apparatus and breast cancer can pave the way for innovative therapeutic interventions and the discovery of biomarkers, potentially enhancing the diagnostic, prognostic, and therapeutic paradigms for afflicted patients. The advancement of such research could substantially expedite the realization of these objectives.

Abstract
CD30, also known as TNFRSF8 (tumor necrosis factor receptor superfamily member 8), is a protein receptor that is heavily glycosylated inside the Golgi apparatus, as well as a tumor marker that is found on the surface of specific cells in the body, including certain immune cells and cancer ones. This review aims to shed light on the critical importance of CD30, from its emergence in the cell to its position in diagnosing various diseases, including Hodgkin lymphoma, where it is expressed on Hodgkin and Reed-Sternberg cells, as well as embryonal carcinoma, anaplastic large cell lymphoma (ALCL), and cutaneous T-cell lymphoma (CTCL). In addition to its role in positive diagnosis, targeting CD30 has been a promising approach treating CD30-positive lymphomas, and there is ongoing research into the potential use of CD30-targeted therapies for autoimmune disorders. We aim to elaborate on CD30's roles as a tumor marker, supporting thus the hypothesis that this receptor might be the aim of cytostatic treatment.

Abstract
Diagnosing cutaneous melanoma is usually straightforward based on these malignancies' histopathological and immunohistochemical features. Nevertheless, melanomas can imitate various other neoplasms, sometimes lacking the expression of conventional melanocytic markers and expressing non-melanocytic ones. Furthermore, divergent differentiation is more often encountered in metastatic melanomas and is still poorly described in primary cutaneous melanomas, and little is known about these patients' prognosis and therapeutic approach. Therefore, we reviewed the literature on undifferentiated/dedifferentiated cutaneous melanomas, and we discuss the histological, immunohistochemical, and molecular profiles of undifferentiated/dedifferentiated cutaneous melanomas to understand these peculiar lesions better and improve their diagnostic algorithm. In addition to this, we also discuss how different genetic mutations may influence prognosis and become potential therapeutic targets.

Abstract
Because almost one fourth of patients with rectal adenocarcinoma (RC) achieve pathological complete response (pCR) after neoadjuvant chemoradiation therapy (CRT), having significantly higher survival rates than those without pCR, the assessment of pCR represents a highly important challenge nowadays. Moreover, recent studies revealed that organ-sparing approaches could represent a reasonable alternative to radical surgery (RS) in patients with pCR, achieving similar long-term outcomes with lower morbidity rates and improved quality of life. Unfortunately, the decision of a rectum-sparing approach should be based only on clinical, endoscopic (with or without biopsy) and radiological methods, that must accurately predict the pCR after neoadjuvant CRT, in the absence of the pathological examination of the RS specimen. Thus, a surrogate parameter called clinical complete response (cCR) emerged, to assess the results of neoadjuvant CRT. The evolving accuracy of recent endoscopic and imaging methods in assessment of cCR and their predictive value for estimation of pCR achievement are presented. The usefulness of combining the results of these evaluation methods (resulting in the development of few nomograms) for a more accurate estimation of pCR, as well as the predictive factors for pCR achievement are also debated. Moreover, the changing landscape of therapeutic approaches based on cCR assessment is discussed, emphasizing the advantages and pitfalls of rectum-sparing approaches, compared to RS. Because there are no reliable methods to estimate with 100% accuracy the pCR, the only way to decrease as much as possible the risk of misleading treatment choices is the multidisciplinary team-based decision.

Abstract
The present study constitutes a retrospective study for patients with hyperparathyroidism surgically operated on at the Department of Thoracic Surgery of the Central Military Emergency University Hospital 'Dr. Carol Davila', Bucharest, Romania (SUUMC), over a period of 6 years. The study aimed to elucidate the diagnostic and surgical attitude for an effective treatment, practiced at SUUMC, Romania. The study group included 55 patients: 41 women and 14 men, diagnosed at the endocrinology department, who underwent various personalized surgeries (Kocher modified incision) for typical and ectopic locations of parathyroid pseudotumor formations (hyperplasia and parathyroid adenoma), to cure the disease. The recommended protocol was followed by immediate and 30-day postoperative evaluation which showed normalization of the blood tests, and improved clinical and imaging anomalies. In conclusion, the thoracic surgeon has the necessary knowledge to perform surgery at the cervical, thoracic-cervical and mediastinal levels. Postoperative, the results of laboratory tests for calcium (Ca) and parathyroid hormone (PTH) gradually returned to normal, as can be seen from the statistical study.

Abstract
Squamous metaplasia occurring within a colorectal polyp is a rare finding, having a reported incidence of approximately 0.44%. The origin of the squamous cells in this type of setting is uncertain (mechanical irritation and chronic inflammation are potential predisposing factors). It has been implied that the significance of squamous metaplasia in colorectal adenomas is that of a preneoplastic lesion for squamous cell and adenosquamous carcinoma, however the evidence to support this statement is scarce. We present a case of a large tubulovillous adenoma located in the sigmoid, with low-grade dysplasia and multiple foci of p16-positive immunoexpression squamous metaplasia in a 54-year-old Caucasian male, presenting with rectal bleeding.

Abstract
Described as a rare anomaly of the placenta, with a reported incidence of 0.02%, mesenchymal dysplasia is a benign condition characterized by placentomegaly, grape-like vesicles and by microscopic features resembling those of a molar pregnancy, such as hydropic villi, cistern formation and dysplastic blood vessels. We report a rare case of placental mesenchymal dysplasia diagnosed in a pregnancy with early symmetric fetal intrauterine growth restriction and a normal karyotype. Based on this case report, we discuss the particularities of this condition, emphasizing the ultrasonography and histopathological findings.

Abstract
Conventional schwannoma represents a benign peripheral nerve sheath tumor derived from Schwann cells, which usually arises in the fourth or fifth decade of life, in the subcutaneous tissue of the distal extremities, or in the head and neck region of adult patients, with no gender predilection. In addition to the classic type, at least 11 different histopathological subtypes have been described and unawareness of these uncommon histopathological entities may lead to diagnostic pitfalls and risk of mistreatment. Recently described in the scientific literature, microcystic/reticular schwannoma is still relatively unknown to both surgeons and pathologists. The purpose of this paper is to highlight its existence by describing an additional case that occurred in the retroauricular area, and to further characterize its clinical, histopathological and immunohistochemical features. We reviewed the literature and compared the current case with others that have been documented thus far, discussing all possible differential diagnoses.

Abstract
Melanomas can exhibit a wide range of unusual morphologies due to the neural crest origin of melanocytes. Several authors have documented variations in size and shape of cells, cytoplasmic features and inclusions, nuclear features and cell architecture. Metastatic melanoma with rhabdomyoblastic differentiation is an extremely rare condition with poor prognosis. Few studies concerning rhabdoid or rhabdomyoblastic differentiation in melanoma are currently available and the current report highlights some of the most important immunohistochemical features of this rare entity. We report on a case of a rhabdomyoblastic metastatic melanoma showing intense positivity for both melanocytic and rhabdoid markers in two cell populations dissociated within the tumor with multiple mismatches in immunomarker expression. Improved recognition of this rare morphological pattern may provide the means for developing new techniques to identify novel therapeutic targets, which would improve the prognostic outlook for these patients.

Abstract
Body stalk anomaly (BSA) is a rare abdominal defect, generally considered to be lethal. Reported prevalence ranges from 0.4 to 3.2 per 100 000 live births. An early prenatal diagnosis offers the possibility of parental counseling and the termination of pregnancy. Also called limb-body wall complex, the anomaly is characterized by finding the intrathoracic and abdominal organs outside the cavity comprised by amnio-peritoneal membrane attached directly to the placenta and the umbilical cord short or absent. We report a case of BSA in a monochorionic-diamniotic twin pregnancy, diagnosed antenatal by the massive midline thoraco-abdominal wall defect, severe scoliosis and absent umbilical cord, presented at fetal ultrasound first trimester examination; portions of the heart, kidney and lung were contained into the placenta. The second fetus was echographically normal. At 18 weeks of gestation, a recommended amniocentesis exam was performed, an abnormal karyotype being excluded through this method. At 33 weeks of gestation, the patient presented with spontaneous preterm rupture of membranes. Delivery occurred by emergency Caesarean section for acute fetal distress; extracted first live fetus was admitted in the neonatal intensive care; the second live fetus with a severe thoraco-abdominal wall defect, fragments of organs included into the placental mass and severe reduction defect of the inferior right limb, deceased at 30 minutes from delivery. The fetus together with the placenta has been sent for histopathological exam. Clinical examination confirmed the diagnosis suspected by ultrasound examination. There are only a few reports in the literature about BSA in multiple gestations, and fewer about twin pregnancies in which only one fetus was affected by this condition.

Abstract
Keratoacanthoma centrifugum marginatum (KCM) is a very rare variant of keratoacanthoma characterized by progressive peripheral growth accompanied by central healing. The tumor has the peculiar ability to involute spontaneously. A careful differential diagnostic with other skin carcinomas or hyperkeratotic lesions is required in order to ensure appropriate clinical management. We report a case of KCM in a 62-year-old man presenting with a solitary, large exophytic, sessile tumor located on the ventral side of the right lower leg, which developed over the course of one year from an initial erythematous papule. The patient presented history of local trauma. To our knowledge, this is the second report in the scientific literature supporting a possible traumatic etiology. Due to its rarity and lack of distinctive histopathological features, KCM poses a difficult diagnostic challenge. Therefore, the importance of an accurate histopathological examination and extensive use of ancillary studies for differential diagnosis is emphasized.

Abstract
BACKGROUND From the first recognition of dysplastic nevi as a pathology per se, many debates have been raised and many histological and immunohistological studies have been conducted in order to establish the true significance of these lesions. Therefore, the aim of this study was to establish if there is a correlation between HMB-45, Melan A and Bcl-2 expression and the grade of dysplasia, as well as between the marker's staining patterns. MATERIAL AND METHODS Ten dysplastic nevi from six female patients were selected and their histological features (size, dysplasia), as well as the immunohistological staining patterns, were studied (HMB-45, Melan A, Bcl-2). The Pearson correlation coefficient and regression was calculated with Windows Excel Data Analysis. RESULTS We demonstrated that there was a notable correlation between the dysplasia and the size of the lesions (r(8)= 0.62 with p-value= 0.052), and also between Melan A and Bcl-2 (a r(6)= 0.73, p<0.05), but we did not obtain a statistically significant correlation between other features (p>0.05). CONCLUSIONS We can affirm, at least in our cases, there is a correlation between the grade of dysplasia and the size of the lesion, and also, that there is a correlation between Melan A and Bcl-2 staining, explained by MITF gene. These results were only partial concordant with those in other studies, therefore a larger number of cases is recommended to be further analyzed in order to clearly draw a conclusion.

Abstract
Associations of different pathologies are not uncommon in every day practice, but association of disseminated infections like cytomegalovirus infection and tuberculosis are quite rare and hard to diagnose. Both are infections which appear frequently in immunocompromised patients and have unfavorable prognosis. We present a case of a 62 year old male with a history of Crohn's disease and tuberculosis which presented with symptoms of relapse and infection. He was treated with immunosuppressive medication and cortisol for the past 6 weeks. Cytomegalovirus (CMV) infection was serologically confirmed. In evolution, he suffered from gastrointestinal hemorrhage and died afterwards due to the hemorrhage and pulmonary infections. Histology confirmed the CMV modification in the lungs and intestines, but also highlighted active and disseminated tuberculosis (TB), bronchopneumonia, osseous metaplasia, hyaline membranes, numerous TB abscesses in the intestinal wall and specific CMV and TB modifications in the liver. The trigger for such important and serious infections remains unclear, for the cause can be represented by the Crohn's disease per se or only by the immunosuppressive treatment. Also, CMV can trigger modifications in immune system and patients with immune-mediated diseases have an increased risk for TB reactivation.

Abstract
Ocular melanoma is a rare malignancy found in clinical practice. In this paper, we present a case of highly aggressive ocular melanoma, which was surgically removed at the Department of Ophthalmology and diagnosed at the Department of Pathology, Emergency University Hospital, Bucharest, Romania, using conventional histopathological techniques. Uveal melanoma, a subset of ocular melanoma, has a distinct behavior in comparison to cutaneous melanoma and has a widely divergent prognosis. Approximately half of patients with ocular melanoma will develop metastatic disease, predominantly with hepatic, pulmonary or cerebral location, over a 10 to 15 years period. No systemic therapy was associated with an evident clinical outcome for patients with advanced disease and overall survival rate remains poor.
