Angiofibroma of the hypopharynx.

Primary extranasopharyngeal angiofibroma is very rare. To date, approximately 60 cases have been reported in the English literature. Only 1 case was confined to the posterior wall of hypopharynx. In August 2000, a 68-year-old man presented with a 6-month history of progressive foreign-body sensation in the throat and intermittent inspiratory stridor. Endoscopic examination of the larynx and pharynx revealed a nonpulsatile, pink-grayish, polypoid mass arising from the posterior pharyngeal wall of the left hypopharynx. Under general anesthesia, this tumor mass was subsequently removed by the endoscopic CO2 laser. The histologic diagnosis was an angiofibroma. Three-year follow-up found no evidence of tumor recurrence or post-operative complications.
