Abstract

Primary leiomyosarcoma of the testis is an extremely rare condition with only a few reported cases in the literature. None has been reported in men of afrocaribean descent. This report describes the first case of a primary leiomyosarcoma in a mixed race man. Several different immunostains were used to confirm the morphological suggestion of a primary intratesticular smooth muscle tumour. Scrotal ultrasound and abdominal computed tomography imaging were used to exclude paratesticular and retroperitoneal pathology. Where reported, primary intratesticular leiomyosarcoma is described as an indolent tumour with the potential for distant metastases. Its occurrence in younger men is usually associated with anabolic steroid abuse. Although the number of reported cases is very few, radical orchidectomy followed by surveillance appears to be the treatment of choice.
