Case 7-2001.

The article presents the case study of a 10-week-old boy with Melanotic neuroectodermal tumor of infancy. The boy was evaluated at Massachusetts Eye and Ear Infirmary, Boston, Massachusetts because of progressive swelling in the region of the right side of the upper lip of two weeks' duration. The boy had been born at full term and had no perinatal problems. On physical examination, the infant appeared well, and there was no craniofacial dysmorphism. There was firm, nontender swelling of the subcutaneous tissue of the right side of the upper lip and of the malar region adjacent to the right nasal ala, with minimal bluish-black discoloration. A diagnostic procedure was performed by Mark S. Volk, Hugh D. Curtin and Michael J. Cunningham.
