Extranasopharyngeal angiofibroma originating from the nasal septum: a case report

Angiofibromas (AFs) originate predominantly in the nasopharynx and posterior nasal cavity. The incidence of these lesions is less than 0.5% among all neoplasms of head and neck. They originate outside the nasopharynx rarely and can therefore be misdiagnosed. The nasal septum is an extremely rare site. Only four cases of extranasopharyngeal angiofibromas arising in the nasal septum have been reported so far. We report here a case of a vascular mass arising from the nasal septum in a 19-year-old boy which was extirpated by submucousal resection endonasally. Histopathology confirmed it to be a case of angiofibroma.
