[Angiosarcoma of the nasal septum]

Abstract

This is a report on a female patient, 37 years old, with a polypous, sessile tumor on the nasal septum covered by smooth mucous membrane. She was treated with local excision. The histological diagnosis was an angiosarcoma, confirmed by immunohistological stain with factor VIII-like antigen, thrombomodulin, and UEA. She currently remains free of the disease 12 months after diagnosis. Angiosarcoma in the head and neck area and especially the localization in the nasal septum are extremely rare. Prognosis, differential diagnosis, metastasis formation, and therapy of this tumor are presented.
