Leiomyosarcoma of the scrotum: a case report with electron microscopy

A case of leiomyosarcoma of the scrotum is presented. The tumor measured 3 X 2.5 X 2 cm and had been present as a slowly enlarging mass in the right scrotum for three months prior to excision. Light microscopy demonstrated the typical interlacing fasicles of neoplastic cells with eccentric cigar-shaped nuclei and electron microscopy confirmed the neoplastic cells to be of smooth muscle origin. A review of the world's literature revealed this to be the fifth reported case of leimyosarcoma confined to the scrotal wall.
