原発性副睾丸平滑筋腫の1例

Abstract

Single case of primary epididymal leiomyoma is presented. The patient was a 53-year-old man whose chief complaint was pollakisuria and terminal miction pain. A painless mass of the thumb tip size was accidentally palpated at the tail of the left epididymis. Left epididymectomy including the mass was performed. The mass was solid, 22×15×13 mm in size, 7.2g in weight and thin red in color. The excised section was grey-yellow. The mass was covered with white capsule. Histologically, the diagnosis was primary epididymal leiomyoma. Postoperative course was uneventful and the patient is doing well now without recurrence. The case was the 38th report of primary epididymal leiomyoma in Japan. A discussion was made on primary epididymal tumor and primary epididymal leiomyoma.
