title: [A case of epidermoid cyst of the testis].
abstract: A 32-year-old business man was admitted with the chief complaint of a right testicular mass without pain. Laboratory findings including serum AFP, HCG, and beta-HCG were within normal limits. Right high orchiectomy was performed under the diagnosis of testicular tumor. The cyst was located at the middle of the testis and was 3.5 X 3.0 X 2.0 cm in size. The cut surface of the tumor revealed a fibrous capsule with a keratin mass in it. Histological diagnosis was a benign epidermoid cyst. This case seems to be the 56th case of epidermoid cyst of the testis reported in the Japanese literature.
