An unusual site for an intraoral schwannoma: A case report.

Schwannomas are benign tumors that are rarely found in the oral cavity. We presented a schwannoma arising from the parasympathetic fibers of the lingual nerve, which is the first in the literature to our knowledge. Its borders in computerized tomography are not well defined despite the contrast medium.

Giant cell granuloma is a reactive osseous proliferation and is histologically benign despite its aggressive clinical course. It usually involves the maxilla and the mandible in the region of the head and neck. It is rare in the ethmoid region.
