SCHWANNOMA DEVELOPED FROM TRIGEMINAL NERVE

Schwannoma named neurinoma, peripheral glioma, perineural fibriblastoma and Neurilemmoma is a ectodermal benign neoplasm which originates from schwann cell or neuro axons. It usually develops in peripheral systems of sensory nerves of gastrointestinal tract, oral cavity, and bone. It occurs more frequently in soft tissue than hard tissue, and is extremely rare in intraoral area. We report a case of Schwannoma that showed large mass on buccal cheek with Rt. midfacial swelling, pain, tenderness to palpation and involvement with maxillary branch of trigeminal nerve. We present this case and review the literature.
