Extranasopharyngeal angiofibroma.
Juvenile nasopharyngeal angiofibromas are vascular neoplasms, which originate characteristically in the posterior lateral wall of the nasopharynx. Although angiofibromas extend beyond the nasopharynx commonly, they rarely originate outside the nasopharynx. Reports of primary extranasopharyngeal angiofibromas have appeared sporadically in the literature. We present an unusual case of an angiofibroma arising from the middle turbinate. The clinical characteristics of extranasopharyngeal angiofibromas do not conform to that of nasopharyngeal angiofibromas. Therefore, they can present diagnostic challenges. A methodic evaluation and a high index of suspicion are essential in establishing the proper diagnosis and treatment.
