title: Coexistence of benign schwannoma and lymphoma in a nasal polyp.
abstract: The existence of a combined benign schwannoma and lymphoma presenting as a nasal polyp has not been described in the English literature. We are reporting this rare combination in a 50-year-old male whose presenting symptoms were nasal obstruction, nasal deformity and headache. Examination of the left nasal cavity revealed a mass which was confined to the nose on computed tomography (CT) scan examination. Histopathology of the mass revealed a major component to be a benign schwannoma and a minor component a large B-cell lymphoma.
