title: Sinonasal fibrosarcoma: a case report.
abstract: Sinonasal fibrosarcoma (SFS) is an infrequent malignant neoplasm. It usually presents as other sarcomas in this region, with nasal obstruction and epistaxis. The final diagnosis is based on the histopathology and immunohistochemistry. We report the case of a 58-year-old man with an 8-month history of left proptosis, recurrent epistaxis and nasal obstruction. Nasal endoscopy confirmed a left nasal neoplasia. CT and MRI showed the extension of the neoplasia, occupying the left nasal fossa and ethmoid sinuses, and eroding the medial wall of the orbit. Complete removal was achieved through endoscopic sinus surgery, preserving the orbit. SFS was found on histopathologic examination. After 4 years of follow-up, nasal endoscopy, CT and MRI imaging show no sign of recurrence.
