Parasympathetic schwannoma of the submandibular gland.

Schwannomas of the submandibular gland have only been documented sporadically throughout the medical literature. We describe a case of schwannoma of the submandibular gland originating from the submandibular branch of the lingual nerve, which carries the preganglionic parasympathetic nerve fibers. The clinical aspect of this tumor is discussed, followed by a brief literature review.
