Abstract
Myiasis is one of the most common skin diseases found in travelers returning from tropical and subtropical regions, where humans living in or visiting the African continent are most commonly infested by C. anthropophaga during the rainy season in regions with a warm climate. Here, we present a case of furuncular myiasis caused by C. anthropophaga in a Serbian patient returning from temporary work in Kenya, where the initial histology of skin lesion mimicked hyperproliferative skin disorder.

Abstract
The present research aimed to determine the clinical and pathohistological characteristics of thyroid gland diseases in adolescents who were previously surgically treated at the Endocrine Surgery Center of the University Medical Center of Serbia from 01/01/2001 to 01/01/2011. The study covered 170 patients of both sexes from the population of adolescents (aged 16 to 20 years) with various malignant and benign thyroid gland diseases. The data for this study were extracted from the medical histories of patients and the electronic database of the Center for Endocrine Surgery. Detailed data analysis included diagnosis, symptomatology, surgical intervention type, and disease stage. The following thyroid status parameters were analyzed from preoperative data: thyroxine (T4), thyroxine free fraction (FT4), triiodothyronine (T3), triiodothyronine free fraction (FT3), and thyroid stimulating hormone (TSH). In addition, the pathohistological features of diagnosed thyroid diseases were also determined, with a special focus on the presence of well-differentiated cancers. Papillary carcinomas were the most common of well-differentiated cancers in adolescents over the ten-year follow-up period. Based on the assessed data, total thyroidectomy was the most commonly used type of surgical intervention in these patients. The conducted research provides essential information related to both the biological characteristics and diagnostics of these cancers and their surgical treatment in such a sensitive population. Moreover, research showed that the clinical presentation of thyroid cancer in adolescents is almost identical to that in adults.

Abstract
The accurate management of testicular germ cell tumors (TGCTs) depends on identifying the individual histological tumor components. Currently available data on protein expression in TGCTs are limited. The human protein atlas (HPA) is a comprehensive resource presenting the expression and localization of proteins across tissue types and diseases. In this study, we have compared the data from the HPA with our in-house immunohistochemistry on core TGCT diagnostic genes to test reliability and potential biomarker genes. We have compared the protein expression of 15 genes in TGCT patients and non-neoplastic testicles with the data from the HPA. Protein expression was converted into diagnostic positivity. Our study discovered discrepancies in three of the six core TGCT diagnostic genes, POU5F1, KIT and SOX17 in HPA. DPPA3, CALCA and TDGF1 were presented as potential novel TGCT biomarkers. MGMT was confirmed while RASSF1 and PRSS21 were identified as biomarkers of healthy testicular tissue. Finally, SALL4, SOX17, RASSF1 and PRSS21 dysregulation in the surrounding testicular tissue with complete preserved spermatogenesis of TGCT patients was detected, a potential early sign of neoplastic transformation. We highlight the importance of a multidisciplinary collaborative approach to fully understand the protein landscape of human testis and its pathologies.

Abstract
Warthin's tumour (WT) is a benign epithelial salivary tumour, one type of salivary adenoma. Histologically, WT is structured of two components, epithelial tissue that often lines cystic formations and lymphoid tissue in the tumour stroma. FNA is a reliable diagnostic approach in the diagnosis of salivary gland lesions allowing a highly accurate categorization of benign tumour-like lesions, benign tumours and malignant tumours. In the proposed Milan reporting system of salivary gland lesions, WT is categorized in the IVA group of benign neoplasms. Accurate cytological diagnosis is straightforward when three characteristic components are present: oncocytes, either isolated or associated in clusters, lymphocytes and lymphoid cells and often an inflammatory/necrotic-like substance. Also, specific features of scintigraphy and radiological imaging contribute to the diagnosis of WT. WT is categorized according to Seifert G. et al in 4 types, depending on the proportions of the epithelial component and lymphoid stroma. Differential cytopathological and pathohistological diagnosis include other salivary gland lesions with lymphoid, oncocytic epithelial and cystic components. In some cases, such as the metaplastic WT variant, there are additional cytopathological and histological diagnostic difficulties. Moreover, bilateral, multicentric or multiple and infrequently seen extra-salivary localizations of WT are associated with further cytopathological diagnostic difficulties. Also, a rare possibility of malignant transformation of the epithelial or lymphoid component of WT as well as possible association with other primary tumours remains a challenge in accurate cytopathological and histological diagnosis of WT.

Abstract
Background Intracranial angiomatous meningioma (AM) is a rare subtype of meningioma. Here, we investigated the clinical and pathological features of AMs. Materials and Methods We performed a retrospective study of 23 intracranial AMs verified by postoperative pathology at Huashan Hospital North between 2013 and 2018. Clinical data, radiological and pathological findings, and information on treatment and outcomes were collected and analyzed. Additionally, the literature on intracranial AMs was reviewed. Results The sample comprised 13 men and 10 women with AMs. The mean age was 54.2 years, and the mean duration of symptoms was 14.9 months. Headache and epilepsy were the most common symptoms. The most common AMs locations were the cerebral convexity and parasagittal/falx region. The rates of vascular signs, homogeneous enhancement, and peritumoral brain edema (PTBE) on magnetic resonance images were high. Histologically, besides typical meningioma cells, AMs had an abundant vascular component and low Ki-67 index. The extent of PTBE was related to microvessel density (MVD) of tumors, but not to the expression of MMP9 or VEGF. Simpson grade I resection was achieved in 15 cases, and grade II resection was achieved in 7 cases. Twenty-one cases were followed up, and they all had favorable outcomes without recurrence. Conclusion AM is a type of meningioma with a rich blood supply and distinct clinical and pathological features. It showed a slight male predominance and was common at the cerebral convexity or parasagittal/falx region. Histologically, it showed benign biological characteristics despite frequent and severe PTBE, and the extent of PTBE was related to MVD of tumors. Simpson I resection is the best treatment, and the prognosis is usually good after total tumor removal, while gamma knife is recommended for small residual tumor.

Abstract
Simple Summary The poultry industry is the most intensive and fastest growing among all livestock production systems, and, in the last decades, it has expanded exponentially due to an increasing demand for meat and eggs. Marek’s disease is a highly contagious and rapidly progressive lymphoproliferative disease. It is one of the most dangerous diseases of those affecting the sector because it causes important economic losses. Although widely controlled by vaccination programs, sometimes chickens are not totally protected, and the presence of virulent field strains can allow outbreaks. This case describes the occurrence of Marek’s disease observed in a breeder chicken flock that reported an increase in mortality rate (+0.4–0.6%) after the 32nd week. Histological analysis has highlighted severe lesions on visceral organs of chickens caused by Marek’s disease, especially in the intestinal tract of a hen that had a tumor mass in the distal part of the cloaca. Immunohistochemical staining confirmed the disease-associated tumor. The aim of this study was to underline the importance of vaccine administration related to the maintenance of proper biosecurity practice, especially in the first week of the raising cycle. In addition, monitoring for disease even after vaccination is crucial to minimize economic loss. Abstract Marek’s disease is widely controlled by vaccination programs; however, chickens are not totally protected, especially immediately after the vaccination when a strong challenge could interfere with the effectiveness of vaccination in the absence of proper biosecurity practice. This case report describes the occurrence of Marek’s disease (MD) observed in a breeder chicken flock reared southeast of Sicily. MD outbreak occurred from 32 to 47 weeks with an increase in weekly mortality rate (+0.4–0.6%). Overall, mortality rate related to Marek’s disease was about 6% at the end of the cycle. Carcasses of chickens found during the occurrence of disease underwent necropsy, and tissues were collected to confirm the infection. Gizzard, cecal tonsil, intestine, spleen and tumor mass were collected and analyzed from a carcass of one hen, 32 weeks old and apparently asymptomatic. Multiplex real-time PCR performed on spleen tissues detected the presence of MD virus pathogenic strain. Macroscopic and microscopic evaluation of the rest of the samples confirmed the neoplastic disease. Moreover, the immunophenotype of the tumor cells was identified as CD3 positive by immunohistochemical (IHC) staining. The vaccinated flock had become rapidly infected with the MD virus, which proves that the challenge of the MD virus was too strong in the rearing house at the beginning of the cycle, causing the outbreak.

Abstract
OBJECTIVES To assess the influence of smoking on histological disease severity and fibrosis in real-world NAFLD patients. MATERIAL AND METHODS Consecutive NAFLD patients were identified with liver biopsies performed between 2008 and 2015. Characteristics such as smoking status and total number of pack years were collected. Biopsies were revised and BRUNT fibrosis and NAFLD activity score (NAS) determined. Patients with a high NAS (≥5) were compared to patients with a low NAS (<5) and with advanced fibrosis (stage 3-4) to patients with no-early fibrosis (stage 0-2). Patients with a history of smoking (current or past smoker) were defined ever smokers. RESULTS Fifty-six patients were included (mean age 49 ± 14.3, 68.9% males and 39.3% history of smoking). Ever smokers had a higher fibrosis score than never smokers; two (IQR 0-3) versus one (IQR 1-1.5) (p = .040). Patients with advanced fibrosis smoked significantly more pack years than patients with no-early fibrosis; 10.6 (IQR 0-25.8) versus 0 (IQR 0-7) (p = .011). There is a weak to moderate correlation between fibrosis stage and number of pack years (Spearman's Rho = 0.341, p = .012). There was no difference in NAS between never and ever smokers; 2.8 ± 1.5 versus 3.3 ± 1.4 (p = .205). Patients with NAS <5 had a median number of pack years of 0 (IQR 0-9) versus a median of 10.3 pack years (IQR 0-24) in patients with NAS ≥5 (p = .127). CONCLUSION Smoking is associated with severity of NAFLD-related liver fibrosis but not with histological disease severity. This supports the recommendation to cease smoking for NAFLD patients.

Abstract
The dynamics of pathomorphological changes in response to infection with plasmid variants of Yersinia pseudotuberculosis was studied in experimental animals. Variability of cell injuries in pseudotuberculosis histopathology depended on the plasmid-associated virulence of the infection agent. Infection with highly virulent two-plasmid strain pYV48:pVM82 MDa and Y. pseudotuberculosis strain with low virulence with the only plasmid pVM82 MDa led to the development of cell destruction (necrosis and apoptosis) in the target organs. Apoptosis predominated in response to infection by plasmid variant pVM82 MDa with low virulence.

Abstract
The national breast cancer screening program has been introduced in Croatia in the second half of 2006 with mammography as the screening method. We investigated the impact of screening mammography on the basic pathohistological characteristics of breast cancers retrieved from the database of large community hospital. The data were collected in the period following the initiation of national mamographic screening program (2007-2011), and compared with the data collected in the period before the program introduction (2002-2006) to explore the possible changing trends. In the screening period 1,320 breast cancers were diagnosed, while in the prescreening period 1,204 breast cancers were diagnosed (p=0.02). We found the reduction of mean tumor size (p=0.039), decrease of the diagnosed non-invasive cancers (p=0.001), and the higher percentage of the diagnosed ductal (p=0.0003) and grade 3 (p=0.038) invasive cancers in the screening period. We also noticed higher percentage of diagnosed advanced breast cancers with unknown tumor size in the screening period (p=0.027). We concluded that the implementation of national screening program did not improve the pathohistological features of breast cancers in our region probably due to low response rate to screening invitation.
