The histological diagnosis was angioleiomyoma. This patient was the first case of angioleiomyoma in and out of Japan. Case 2 was 46 years old. A mass measuring 1.8×1.2×1.0 cm was found at the tail of the left epididymis. This mass was diagnosed histologically as leiomyoma. This patient was the 25th case of leiomyoma in Japan. 2. A total of 107 cases of primary epididymal tumor have been reported in Japan. The tumor was benign in 74 cases (69.2%) and malignant in 33 cases (30.8%).
