Epithelial ovarian tumor in a phenotypic male.

Laparotomy in a 41-year-old married man with non-treated left cryptorchidism revealed female internal genitals on the left side, and an epithelial ovarian tumor of intermediate malignancy. Germinal malignancies are frequent in intersexes, but non-germinal gonadal neoplasms are rare. This is the second reported case of epithelial ovarian tumor in intersexes, and the first case of epithelial ovarian tumor in an intersex registered as male.
