Introduction: Bone tumors are rare neoplasms whose therapy depends on the location. Pelvic bones represent a special anatomical entity diagnosis and therapy of pelvic tumors in addition to the pathohistological type largely depends on the anatomical specifics of that region. Aim: The aim of this study was to show the frequency, as well as clinical and pathological characteristics of primary and secondary tumors of the pelvic bones. Material and methods: The research as a descriptive study in the period from January 1, to December 31, 2019 at the Institute of Pathology of the Medical Faculty of the University of Belgrade and includes 33 patients. Demographic, clinical and radiological data were obtained from the Bone Tumor Registry. Statistical processing and analysis were done in the Statistical Package for Social Science SPSS Windows version 22 (IBM Chicago, Ilinois, USA). Results: Out of 33 patients, 55% had secondary pelvic tumors, primarily cancer metastases (37%). In 21% of cases, primary malignant bone tumor as diagnosed, and in 12%, primary benign bone tumor. Hematopoietic neoplasms were verified in 12%. Conclusion: Pelvic bone tumors are not common, but these neoplasms, in orthopedic oncology, represents their malignant biological behavior are of great importance. The most common primary malignant tumor in adults is chondrosarcoma, and in children Ewing sarcoma. Highest frequency for pelvic bone metastases has lung cancer. Plasmacytoma in adults, Langerhans cellular histiocytosis in children are hematological neoplasms seen at this site.

Introduction: Skeletal anomalies are a heterogeneous group of disorders including changes in bone shape, size, and density that cause abnormalities of the extremities, trunk, and head. They rank second in Europe in the frequency of all congenital anomalies. The most common skeletal anomalies include head, face and limb anomalies. Aim: The aim of this study was to determine the frequency of skeletal anomalies and their association with anomalies of internal organs, as well as to show the age of the mother and the gestational week of the fetus with established skeletal anomalies. Material and methods: All fetal and neonatal autopsies in the period from January 1, 2018 to December 31, 2020 at the Institute of Pathology "Djordje Joannovic" of the Faculty of Medicine University of Belgrade were analyzed. In the mentioned period, 580 fetal and neonatal autopsies were performed. Clinical data were obtained from the Gynecology and Obstetrics Clinic "Narodni Front" on the basis of completed requests for clinical autopsy. Descriptive statistics methods were used (data are presented as absolute numbers and percentage frequencies). Results: The most common skeletal anomalies are divided into seven groups: spina bifida (20; 33.34%), limb anomalies (16; 26.67%), head and face bone anomalies (15; 25%), joint anomalies (2; 3.33%), achondroplasia (3; 5%), osteogenesis imperfecta (2; 3.33%) and other anomalies (2; 3.33%). The most common associated anomalies were central nervous system (CNS) abnormalities, followed by heart and kidney abnormalities. The youngest mother was 15 years old, and the oldest was 47 years old. The mean age of the mothers was 30 years. Conclusion: In our study, the most common anomaly was spina bifida, while limb anomalies and craniofacial anomalies are next in frequency. Skeletal anomalies were often associated with anomalies of the heart, kidneys, and CNS. They were mostly diagnosed between the 22nd and 27th gestational week. Our results showed that skeletal anomalies are more common in fetuses or neonates of mothers older than 30 years.

Introduction. Cementoblastoma is an uncommon tumor of the jaws that originate from odontogenic ectomesenchyme, characterized by proliferating cementum-like tissue. Case Outline. We present the case of a cementoblastoma in the mandible with atypical radiographic image: no well-defined borders and no radiolucent rim. Apart of that, taking into account data from the literature review, different clinicopathological, and radiographic presentations of tumors and lesions that may resemble cementoblastoma are discussed. Conclusion. Cementoblastoma must be removed as soon as possible, together with the associated tooth. Recurrence rate is a relevant phenomenon and is estimated to 11.8%, so the long-term follow-up is mandatory.

Introduction/Objective Postmortem examination has a significant role in evaluating the quality of health care. The objective of the paper is to analyze the cause of death as determined by postmortem examination in patients who had undergone emergency hospitalization and had subsequently died within 24h, as well as the factors that contributed to the fatal outcome and correlation with available clinical data. Methods the analysis included autopsy reports and protocols, as well as clinical data from medical records and autopsy referrals during the three year period (2018-2020) for patients who had undergone a postmortem examination at the Insitute of Pathology, Medical Faculty, University of Belgrade. The correlation between the clinical diagnosis and postmortem findings was evaluated using Goldman criteria. Results the patients analysed were predominantly male (52/90; 58%). Women were statistically significantly older than men (p=0.024). The most common clinical diagnosis was cardiovascular disease (32.2%). The majority of the patients reported experiencing the first symptoms a few hours before seeking medical help (80%). The majority of the patients were being treated for chronic disease (80%) before hospitalization. The immediate cause of death determined by postmortem examination was most commonly heart failure (38/90, 42.2%). The most common clinically unrecognised causes of death include: bronchopneumonia (8/90), myocarditis (3/90), acute ischemic lesion/acute myocardial infarction (3/90) and bowel infarction (3/90). Conclusion the correlation between clinical and postmortem findings is very important because it enables the discovery of diagnostic and treatment errors and promotes new knowledge crucial for medical advancement.
