Abstract
A 43 year old female was admitted suffering from nasal bleeding. A tumor was found to be filling the right nasal cavity. CT and MRI examination showed a mass lesion of about 2.5 cm in the upper right nasal cavity but the paranasal sinuses were intact. By lateral rhinotomy the tumor proved to originate from the nasal septum near the olfactory mucous membrane and was completely removed. Histological examination revealed a benign fibrous histiocytoma. There is no evidence of recurrence in 3 years of follow-up. This is the first reported case in Japan of a benign fibrous histiocytoma originating from the nasal septum.
