Adult Pleomorphic Rhabdomyosarcoma of the Peroneal Compartment; Rare Case Report

Abstract

Pleomorphic Rhabdomyosarcoma (RMS) is a rare form of soft tissue sarcoma in adults. Due to the rarity of adult RMS, information regarding its clinical and biologic characteristics is very limited. I report a case of embryonal RMS of lower extremity involving the right leg peroneal compartment in a 37-year-old man. There was metastasis of the tumor to the ipsilateral inguinal lymph nodes at diagnosis. The patient underwent surgery with enbloc excision of the tumor from the peroneal compartment and ipsilateral inguinal lymphnode biopsy. Histopathological examination revealed highgrade pleomorphic RMS and postoperatively he under went chemotherapy and six cycles of radiotherapy.
