Malignant melanotic neuroectodermal tumor of infancy: a case report

We present a case of melanotic neuroectodermal tumor in the maxilla that followed an aggressively malignant course. In the first biopsy the tumor showed a classical histological picture, while in the last biopsy only malignant undifferentiated cells were evident. The tumor recurred twice after excision, and in spite of radiotherapy and various chemotherapeutic measures the patient died within 16 months of onset. Similar cases reported in the literature are discussed.
