[Bilateral simultaneous epididymal leiomyoma: a case report].

: Primary epididymal leiomyoma is relatively rare. We experienced a case of bilateral simultaneous primary epididymal leiomyoma. A 61-year-old man visited our clinic, with the chief complaint of bilateral painless nodules in the scrotum. Each nodule was palpated at the tail of each epididymis (the diameters of these nodules were 12 mm on left and 5 mm on right). We followed the patient for 18 months. Since the nodules were increasing in size, the nodules were surgically removed. Histological examination revealed primary leiomyomas of the epididymis.
