Primary Extraosseous Ewing Sarcoma of the Vulva: Unravelling the Mystery of a Common Tumor in an Uncommon Site.

Primary vulvar Ewing sarcoma (ES) is exceedingly rare, particularly in postmenopausal women. To date, only 14 cases have been confirmed through molecular cytogenetic analysis. We report the case of a 55-year-old woman presenting with a painful, ulcerated vulvar mass.

Human Epidermal Growth Factor 2 (Her-2) Expression in Gastric and Gastroesophageal Carcinomas: A Clinicopathological Evaluation in a Tertiary Care Institute.

Introduction Gastric carcinoma is a significant global health concern, known for its high mortality rate. HER-2 overexpression is observed in a notable proportion of gastric carcinoma and is associated with a worse prognosis. However, HER-2 expression enables targeting the protein by monoclonal antibodies that improve overall survival in HER-2-positive gastric cancers.

Unraveling the Clinicopathological Diversity and Subtypes of Rhabdomyosarcoma: A Study From a Tertiary Care Center.

Background and objective Rhabdomyosarcoma (RMS) is a rare and malignant mesenchymal tumor characterized by skeletal muscle differentiation. While it is a common soft tissue sarcoma in children, its incidence significantly decreases with advancing age, rendering it exceptionally rare in individuals aged more than 45 years. This study aimed to shed light on the clinicopathological diversity and subtypes of RMS, thereby providing a comprehensive overview for enabling diagnostic precision and therapeutic strategies in treating this infrequently encountered malignancy in adults.

Unveiling Variations: A Comprehensive Comparison of Five Globally Used Thyroid Cytology Reporting Systems With Histopathological Correlation.

Introduction Accurate cytological assessment is pivotal for managing thyroid lesions and various global reporting systems are in use, such as the globally acclaimed The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC), alongside other reporting systems namely, the Japanese Reporting System for Thyroid Aspiration Cytology (JRSTAC), Italian Consensus for the Classification and Reporting of Thyroid Cytology (ICCRTC), the UK Royal College of Pathologists System for Reporting Thyroid Cytopathology (UK RCPath), the Royal College of Pathologists of Australasia and Australian Society of Cytology Classification System (RCPA/ASC). Notably, variations exist among these systems which are influenced by country-specific statistics. Given the lack of large-scale data in India and the difference in prevalence of diagnostic entities compared to the western population, this study aimed to identify reporting systems suitable for the Indian population focusing on distinguishing neoplastic from non-neoplastic lesions.

Coxsackievirus and Adenovirus Receptor (CAR) Expression in Autopsy Tissues: Organ-Specific Patterns and Clinical Significance.

Coxsackievirus and adenovirus receptor (CAR) homologs have been identified in many species, and their proteins appeared to be highly conserved in evolution. While most of the human studies are about pathological conditions, the animal studies were more about the physiological and developmental functions of receptors. The expression of CAR is developmentally regulated, and its tissue localization is complex.

targets interleukin-8 and cyclooxygenase-2 in human prostate cancer progression.

Background: Prostate cancer (PC) is a common noncutaneous malignancy in men. The incidence of PC is increasing at an alarming rate across the globe. Progression of PC is associated with elevated levels of interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2) in malignant cells.
