Adenomatoid tumor of the testis in a child

Abstract

Adenomatoid tumors are rare benign neoplasms thought to be of mesothelial origin. Although most reported cases arise from the epididymis, rare cases have been reported in the spermatic cord, testicular tunica, ejaculatory ducts, prostate, and suprarenal recess. We describe a 4.5-year-old boy who presented with a relatively asymptomatic right testicular mass that was resected and confirmed to be adenomatoid tumor of the testis by histopathology. Because of its rarity, the clinical and histopathologic aspects are discussed.
