A Case of Neurilemmoma in the Nasal Vestibule

ABSTRACT

A schwannoma, also known as neurilemmoma, is a relatively rare benign tumor originating from the schwann cells of the nerve sheath. It occurs along any somatic, sympathetic and cranial nerves except the olfactory and optic nerves. It occurred most frequently in the head and neck but rarely in the nasal cavity and paranasal sinuses. Occurrence was especially rare in the nasal vestibule. Recently we experienced an unusual case of the schwannoma involving the left nasal vestibule. The mass was completely removed via a sublabial approach and histopathological examination and immunohistochemical staining study confirmed the schwannoma. We report this case with review of literatures.
