Mixed germ cell tumor after bilateral orchidopexy in persistent Müllerian duct syndrome with transverse testicular ectopia.

The persistent müllerian duct syndrome is characterized by the retention of müllerian derivatives (fallopian tubes, uterus) in patients otherwise normally virilized, usually with cryptorchidism or an inguinal hernia. Very rarely, this syndrome is associated with transverse testicular ectopia, which designates the condition when both testes descend through the same inguinal canal into the same scrotal sac. We report on a patient with both conditions, who had T1N2M0 scrotal mixed germ cell tumor of the testis (teratoma and embryonal carcinoma), 18 years after bilateral orchidopexy. The literature concerning this uncommon association is reviewed.
