title: [Epidermoid cyst of the testis: a case report].
abstract: A 28-year-old man was admitted to our department with the chief complaint of a painless nodule in the left scrotal content. Physical examination revealed that a small, thumb-finger sized, hard mass with a smooth surface was palpable at the upper part of the left scrotal content. With the preoperative diagnosis of testicular tumor, the left testis was explored under ischemia. Appearance of the testis was normal and the mass was felt in the upper portion of the testis. Since the mass was suspected to be malignant, left radical orchiectomy was performed. The histological diagnosis was epidermoid cyst of the testis. Sixty-five cases of testicular epidermoid cyst including this case have been reported in the Japanese literature, and are reviewed briefly here.
