title: [Adenomatoid tumor of testicular tunica albuginea: a case report].
abstract: Adenomatoid tumors are uncommon neoplasms of the paratesticular tissues. We report a case of an adenomatoid tumor of the testicular tunica albuginea. A 54-year-old man presented with a painless right intrascrotal mass. Serum levels of HCG-beta and AFP were within normal limits. Scrotal ultrasonography showed an oval-shaped low echoic lesion located on the surface of the testis. The patient underwent right partial orchiectomy. Histological examination revealed adenomatoid tumor of the tunica alubuginea testis. Adenomatoid tumors of the testicular tunica alubuginea are rare. Examination of tumor markers, ultrasound studies and diagnoses of frozen sections can prevent needless orchiectomy.
