A CASE OF ADENOMATOID TUMOR IN THE TESTIS

Abstract

The patient was a 30-year-old man with a painless nodule within the right hemiscrotum. Serum levels of tumor markers (HCG, HCG-β, and AFP) were within normal limit. The patient underwent operation to determine the nature of the nodule. The nodule was located inside the tunica albuginea at lower portion of the right testis and sharply demarcated. After vascular occlusion of the cord, the nodule was excised. The frozen section confirmed an adenomatoid tumor. The vascular occlusion was released, and the wound was closed. The nodule was round in shape, 7mm in diameter, and solid. On cut section, it was uniformly white. Microscopically the nodule was composed of epithelium-like cells and fibrous stroma. Epithelium-like cells formed glandular or tubular structures lined by flattened, cuboidal or columnar cells, some of which contained vacuoles, which were negative for mucin by PAS stain. Adenomatoid tumor in the testis is extremely rare. Careful palpation, examination of tumor markers and ultrasound studies would prevent unnecessary orchiectomy.
