[Intracranial manifestation of so-called "melanotic neuroectodermal tumor of infancy"--a choristoma with neural crest

A case is reported of so-called "melanotic neuroectodermal tumour of infancy" (= MNTI) in a female newborn. The tumour, whose localization was intracranial, but extracerebral, could be removed subtotally. A further 22 cases of the MNTI with neurocranial manifestations reported in the literature, but differing from our case in their extracranial growth, are listed for comparison. We believe that the neural crest is the histogenic origin of the MNTI and, therefore, our proposed definition is: "Christoma with neural crest potencies."
