Serous cystadenoma of the epididymis.

Tumors reminiscent of müllerian epithelial tumors of the ovary have been reported outside of the ovary, including in the pancreas and paratesticular region. The latter are most commonly serous tumors of borderline malignant potential and involve the tunicae. We present the first case of a serous cystadenoma of the epididymis in English reports with a brief literature review.
