[Pigmented neuroectodermal tumor (melanoameloblastoma)].
A pigmented tumor (melanoameloblastoma) in a 4-month-old infant localized in the upper jaw is described. The tumor consisted of cells with melanin granules in the cytoplasm. The detected neurosecretory granules and melanosomes in the parenchymal cells of the tumor suggest to be of neuroectodermal origin.
