title: [Melanotic neuroectodermal tumor in a newborn].
abstract: The tumor consists of two types of cells: small with abundant processes cells capable of dividing and probably being neuroblasts, and the big melanocytes forming bands and glandular-like structures. Tumor cells (mainly melanocytes) express pancytokeratins, S-100 protein, neuron-specific enolase, synaptophysin and melanin antigen. These data are the additional indication that melanotic neuroectodermal tumor is the derivative of the neural crest.
