title: Columellar schwannoma.
abstract: Schwannomas of the nose or paranasal sinuses are very rare. In fact, only 19 cases of schwannoma of the nasal septum have been reported in the otolaryngology literature. In all of those cases, only the cartilaginous or bony septum was involved. To the best of our knowledge, no case of soft-tissue involvement of the columella has been documented until now. We report a case of a columellar schwannoma in a 57-year-old white man. The mass was easily palpated on physical examination, and it was removed surgically. We summarize this case and discuss the incidence, general characteristics, radiographic findings, pathology, and treatment of schwannomas.
