[Epidermoid cyst of the scrotum: report of a case].

A 61-year-old male visited our hospital with the chief complaint of a mass in the right scrotum on October 4, 1985. Under the diagnosis of intrascrotal tumor, the mass was resected surgically. It was a subcutaneous tumor, and had no relation to any intrascrotal organ, such as testis, epididymis or spermatic cord. The mass was 7 x 6 x 5 cm. Pathological diagnosis was epidermoid cyst of the scrotum. Epidermoid cyst of the scrotum is a rare disease and only 7 cases have been reported in Japan.
