Recurrent plexiform schwannoma in vestibular mucosa.

Schwannoma, also called neurilemmoma, is a benign neoplasm of peripheral nerve sheath. An infrequent location of a multiple intraoral plexiform schwannoma arising on the branches of the facial nerve in the vestibular mucosa of a young male patient is here discussed. Surgical treatment has been discussed on the base of histological findings and diagnosis.
