SCHWANNOMA OF THE MANDIBLE

Schwannoma is a benign neoplasm originating from Schwann's cell. It in volves neurons and axons of peripheral nerves. This tumor has a predil ection for the head and neck region, and often occurs as soft tissue l esion. Intraosseous sheath tumors are rare, comprising less than 1% of all bone tumors; the mandible is the most common site. The literature reports only 30 acceptable cases of schwannoma of the mandible. We re port a new case of schwannoma that is unusual in its intraosseous loca lization and the patient's comparatively young age.
