Epidermoid cyst of the testis--benign teratoma in an adult. Case report.

Epidermoid cyst of the testis, which is regarded as benign monodermal development of differentiated teratoma and comprises less than 1% of all testicular tumors, was found within the tunica albuginea in a 23-year-old man. Following peroperative histologic confirmation of its benign nature, the cyst was locally removed, thereby avoiding orchiectomy.
