Melanotic neuroectodermal tumor of infancy: an important mimicker of paratesticular rhabdomyosarcoma.
We report a case of a paratesticular tumor in a 6-month-old infant. This tumor was originally believed to represent a poorly differentiated sarcoma of the cord but upon further pathological consultation it was recognized as a rare melanotic neuroectodermal tumor of infancy involving the epididymis. Since the former is a highly aggressive lesion and the latter an indolent tumor, treatment of these 2 entities differs markedly. Therefore, although the histological distinction between these lesions is often difficult, it is of critical importance.
