Myxoid chondrosarcoma of the scrotum: a case report and review of the literature

Abstract

Extraskeletal myxoid chondrosarcomas are relatively rare soft tissue malignant tumours, most commonly located in the extremities. Their occurrence in the genitourinary tract is extremely rare. We present a clinical case report of an extraskeletal myxoid chondrosarcoma originating in the scrotum.
