description

Summary We present a case of a malignant peripheral nerve sheath tumor [MPNST] of the maxilla corresponding to a 12 year old male who had a painful, ulcerated rapid growing tumor. Histology revealed the presence of a tumor consisting of fusiform cells with abundant mitosis, with negative cytokeratins, actin, desmin, myoglobin and factor VIII. In contrast, the protein S-100 was positive. MPNST was not associated with signs of Neurofibromatosis Type 1. The patient was surgically intervened and received radiotherapy, then died within 10 months posterior to surgical intervention after suffering recurrence.
