Pathology consultation. Melanotic neuroectodermal tumor of infancy.

The melanotic neuroectodermal tumor of infancy is a usually benign neuroectodermally derived tumor with a predilection for the anterior maxilla of children who are less than 1 year of age. The lesion is considered to be readily treated by conservative excision, but it should be regarded as potentially malignant, even though there is infrequent expression of such malignancy.
