Melanotic neuroectodermal tumor of infancy: evidence for multicentricity.

The melanotic neuroectodermal tumor of infancy (MNTI) is a rare neoplasm that is believed to be derived from cells of the neural crest. This case demonstrates a multicentric distribution of the MNTI. The possibility of a multicentric variant of benign MNTI is discussed with respect to both the present case and previously described reports. Suggestions for evaluation and surgical management are given.
