[Melanotic schwannoma of the temporozygomatic region]. / Schwannome mélanocytique de la région temporozygomatique.

ABSTRACT

INTRODUCTION: Melanotic schwannoma is a rare benign tumor, which arises from nerve sheath cells. Melanotic differentiation is its most histologic characteristic. CASE REPORT We report a case of melanotic schwannoma arising in the temporozygomatic region for a man of 38-year-old. Outcome was favourable after tumor resection. DISCUSSION: This benign neoplasm occurs pronominally in spinal nerve roots. Craniofacial locations are rare. Most melanotic schwannomas are slow growing tumors, but prognosis can be poor because of local recurrence or malign behavior, especially when multiple lesions are present and/or involve the Carney complex.
