A case of bilateral epididymal leiomyomas is reported. A 62-year-old man was referred to our hospital under the suspicion of left testicular tumor. A small hen-egg sized painless mass was palpated in the left scrotum and a little-finger-tip-sized mass in the right scrotum. At the operation, bilateral epididymal tumors were revealed, left high orchiectomy and right epididymectomy were performed. Gross evaluation revealed elastic hard tumors at the tail of bilateral epididymis. The left tumor was 40mm in diameter and the right was 10mm. On the cut surface, the tumors were yellowish and solid. Histopathologically they were diagnosed as epididymal leiomyoma. We reviewed 75 cases of epididymal leiomyoma reported in the Japanese literature. Bilateral cases accounted for 21% of the 75 cases.
