title: Melanotic neuroectodermal tumor of infancy in the epididymis. Case report and literature review.
abstract: We report a case of melanotic neuroectodermal tumor that originated in the right epididymis of a 4-month-old Japanese male and review reports of similar cases. Since we could not exclude malignant disease preoperatively, we performed a radical orchiectomy. Histopathological and immunohistochemical studies revealed features characteristic of a melanotic neuroectodermal tumor. Imaging studies showed no distant metastases.
