Recurrent melanotic neuroectodermal tumor of infancy: report of case and tumor heterotransplantation studies.

Abstract

A fifth case of rapidly recurring melanotic neuroectodermal tumor of infancy is reported. The possibility of recurrence and subsequent encroachment on vital facial structures is emphasized. Vigorous bony curettage at initial excision of this benign lesion may aid in the preventing recurrence. Heterotransplantation studies disclosed the benign nature of the MNTI cells.
