title: Extranasopharyngeal angiofibroma of the nasal septum: a rare clinical entity.
abstract: Angiofibromas (AFs) are benign, potentially local aggressive, and rich vascular neoplasms that originate from posterior lateral wall of the nasopharynx in adolescent males. However, they could be encountered in sites other than nasopharynx. The maxillary sinus is the most common location of extranasopahryngeal AFs. The nasal septum is an extremely rare location, and only 15 cases had been reported in literature. In this present case, an unusual extranasal AF originating from the anterior part of the nasal septum is reported with its clinical, laboratory, and treatment options and theories proposed to explain the origin of extranasopharyngeal AFs are discussed.
