Carcinosarcoma of the Nasal Septum: A Case Report and Review of the Literature

We report a case of a 62-year-old man with epistaxis and right-sided nasal obstruction. Nasal endoscopy revealed an exophytic mass arising from the anterior septum that extended posteriorly to the osteo-meatal complex. Excision with endoscopic sinus surgery was performed. Carcinosarcoma was diagnosed based on histopathology and immunohistochemical studies. The patient declined surgery and opted for chemoradiation therapy for the residual tumor. Six weeks after completion of the treatment, clinical resolution of the right nasal mass was noted. Carcinosarcomas are rare and rapidly growing tumors that have a high recurrence rate and are associated with poor patient prognosis. This report emphasizes the need for patients with prolonged nasal obstruction and epistaxis to consult otolaryngologists and undergo nasal endoscopy for definitive diagnosis and appropriate treatment.
