A case of male adenomatoid tumor of tunica albuginea of the testis is reported. A 45-year-old man referred to our hospital because of intrascrotal mass on the right side. The mass increased in size for eight months. Then we excised the tumor, and spared the right testis. The tumor was arising from the tunica albuginea of the testis with a pedicle. The histological diagnosis was adenomatoid tumor. Adenomatoid tumor is a rare benign tumor. A total of 97 cases of adenomatoid tumor of epididymis have been reported in males, but only 23 cases of adenomatoid tumor of the testis have been reported in Japan. Herein, 24 cases of adenomatoid tumor of testis including our case are discussed and reviewed.
