[Schwannomas of the lingual nerve].

Schwanomas in extracranial head and neck region are an uncommon tumour, but when refered to its origin in the parasympathetic nerve fibers are extremely rare. We describe a case of schwanoma of the right submandibular gland originating from the parasympathetic branch of the lingual nerve, and we discuss about the clinical, diagnostic and therapeutic aspects of this rare tumour and a literature review of the recent cases.
