Cytologic diagnosis of a melanotic neuroectodermal tumor of infancy occurring in the cranial bones.
Melanotic neutroectodermal tumor of infancy (MNTI) is a rare, usually benign tumor commonly occurring in the maxilla. MNTIs at unusual sites like the cranium clinically mimic malignant small round cell tumors. Consequently, a correct preoperative cytologic diagnosis of MNTI at these sites helps in the surgical management of the patient. We report on a cytologically diagnosed case of MNTI in the frontotemporal region of the skull in an infant. Aspirates from the lesion were cellular, with a bimodal population mainly of small neuroblast-like cells admixed with a few large epithelioid cells with melanin granules. In the present case, following the cytologic diagnosis a wide local excision was carried out, and the histologic examination confirmed the cytologic diagnosis. Diagn. Cytopathol. 1999;21:280-283.
