Extranasopharyngeal angiofibroma of the head and neck in women.

摘要

Extranasopharengeal angiofibroma of the head and neck in women is very rare, and clinical characteristics do not confirm to that of nasopharyngeal angiofibroma. We present clinical characteristics, etiology, preoperative evaluation, and management of 3 unusual cases of angiofibroma, 1 case originating from larynx and the other 2 cases from nasal septum in women. Endolaryngeal endoscopic excision for laryngeal and local excision for septal angiofibromas were performed. The patients are free of disease. In the etiology of extranasopharyngeal angiofibroma, we suspect that ectopic tissue may become located further away than usual place and may have been the cause of the extranasopharyngeal location. Computed tomography scan, magnetic resonance imaging, and carotid angiogram are valuable in the diagnosis of extranasopharyngeal angiofibroma. Excision of the mass is the treatment of choice, and recurrence is rare.
