Epidermoid cyst of testicle. Ultrasonographic characteristics.

Epidermoid cyst is a benign lesion of the testis which represents approximately 1 per cent of all testicular tumors. We describe a case in which preoperative ultrasound of the testis suggested a benign testicular lesion, thus permitting testis-sparing surgery. The proper management of this lesion remains a source of urologic controversy, and we review the rationales for both radical orchiectomy and simple excision.
