Abstract

 Aim: This study aimed to find out rhabdomyosarcoma’s (RMS) histopathological and immunohistochemical features. Settings: The current study was carried out at the Department of Pathology, Section of Histopathology, Khyber Teaching Hospital Peshawar. The study duration was between from 1st January 2015 to 30th of December 2020. Results: In the current study, all the 300 occurrences were found to be relevant. The most prevalent rhabdomyosarcoma was embryonal rhabdomyosarcoma (ERMS) (87.4%), followed by alveolar rhabdomyosarcoma (ARMS) (9.4%). In the current study we found that embryonal rhabdomyosarcomas was most frequent in males (64%). ERMS were 16.1 percent found in the genitourinary system followed by neck and head region (46.7%). Most samples displayed positive Desmin and MyoD1 immunohistochemistry staining. Conclusions: It is consistent with previously published rhabdomyosarcoma data from all across the globe that our patients' epidemiologic information and microscopic findings are consistent with one other.
