A case of melanotic neuroectodermal tumor of infancy(MNTI) in 5 month old girl is presented with review of the literature. The review of literature indicated that there have been 189 reported cases of this lesion and there were 9 cases of malignant tumor for a rate of 4.8%. This rate of malignancy is very high in view of the fact that the tumor has been described as benign. And immunohistochemical study using avidin-biotin conjugate method demonstrated that this tumor had been originated from neural crest.
