retinal anlage tumor

mel·a·not·ic neu·ro·ec·to·der·mal tu·mor of in·fan·cy

a benign neoplasm of neuroectodermal origin that most often involves the anterior maxilla of infants in the first year of life. It presents clinically as a rapidly growing blue-black lesion producing a destructive radiolucency; histologically, it is characterized by small, round, undifferentiated tumor cells interspersed with larger polyhedral melanin-producing cells arranged in an alveolar configuration.
