Adenomatoid tumor is a benignmesothelialtumor, which arises from the lining of organs. It generally presents in the genital tract, in regions such as the testis and epididymis. It is the second most common extratesticular scrotal mass, after lipoma, and accounts for 30% of these masses. It also has been found in the pancreas.
