Adenomatoid tumor of the male genitourinary tract is a rare benign neoplasm thought to be of mesothelial origin. In exceptional cases, these lesions may involve the testicular parenchyma, of which there are only 9 published cases in the literature. The authors describe a rare case of a testicular tumor in a 41-year-old male with normal tumor markers. Histopathology and immunohistochemical studies revealed an adenomatoid tumor with intratesticular growth. No involvement of the epididymis or testicular membranes was identified. The morphological clues leading to the correct diagnosis of adenomatoid tumor and the possible histogenesis and differential diagnosis are discussed.
