[A case of adenomatoid tumor of the testis treated by testis-sparing surgery: a case report].
A 44-year-old man was referred to our hospital with a chief complaint of a painless left intrascrotal mass, palpable at the lower portion of the left testis. Serum levels of tumor markers, human choriogenic gonadotropin (hCG), hCG-beta, and alpha fetoprotein were within the normal limits. Ultrasonography revealed a hyperechoic mass 13 mm in diameter, which was demonstrated as a hypovascular tumor by Gadrinium-enhanced magnetic resonance imaging. Since the tumor was diagnosed as a benign tumor by frozen section examination intraoperatively, testis-sparing surgery was performed. Histological examination revealed adenomatoid tumor originating from the tunica alubuginea of testis. Adenomatoid tumor of the testis is a rare benign tumor, and the present case is the 36th one in the Japanese literature.
