Epididymal melanotic neuroectodermal tumor of infancy

Six melanotic neuroectodermal tumors of infancy arising in the epididymis were reported previously. Each followed a benign clinical course. In the seventh case of such a tumor, reported herein, an elevated serum alpha-fetoprotein level returned to normal following excision of the tumor. Urinary and serum tumor markers may be useful for following the course of these tumors in the future.
