title: Melanotic neuroectodermal tumor of infancy. A case report of paratesticular primary with lymph node involvement.
abstract: A 17-month-old boy had a melanotic neuroectodermal tumor of infancy in the left paratesticular region affecting the retroperitoneal lymph nodes. Immunohistochemical and ultrastructural study showed phenotypical diversity of the proliferating cells within a spectrum of neuroectodermal differentiation. Urinary catecholamine levels were initially elevated but returned to normal values after complete eradication of the tumor. The patient received chemotherapy and is now well, without evidence of disease 28 months after surgery.
