Concomitant bilateral testicular epidermoid cysts

Epidermoid cyst of the testis is a rare benign germ cell tumor, comprising 1-2% of all resected benign testicular masses. Approximately 300 cases have been reported to date. Unilateral involvement has often been reported in the English literature. However, bilateral occurrence is very rare and to the best of our knowledge, there are only 3 previous reports of bilateral testicular epidermoid cysts. The fact that they are completely benign makes them amenable to treatment by local excision, thereby saving patient from orchidectomy. Recognition of their characteristic ultrasonographic features is very important to avoid unnecessary intervention. We present here, a case of bilateral epidermoid cyst in which characteristic ultrasound (US) findings allowed testis-sparing enucleation instead of radical orchiectomy.
