What is the most common benign tumor of the scrotum, commonly found in the epididymis?

• A. Adenomatoid tumor
• B. Fibroma
• C. Lipoma
• D. Hemangioma

Answer: (A)

Adenomatoid tumor is the most common benign tumor arising in the epididymis and thus the scrotal lesion most often seen in this location. It’s a small, well-defined, solid mass that typically sits in the epididymal region and remains separate from the testis on imaging. Because of its epidemiology and location, it stands out as the top choice when evaluating a benign extratesticular mass of the scrotum. Fibroma, lipoma, and hemangioma can occur in scrotal tissues, but they are much less common specifically in the epididymis, and their imaging features don’t have the same classic association with epididymal origin as the adenomatoid tumor. The mesothelial origin and the characteristic extratesticular, well-circumscribed appearance help explain why this tumor is the best answer.
