Ectopic Tonsillar Tissue in the Hypopharynx; A Case Report

Abstract

A rare case of ectopic tonsillar tissue in the hypopharynx, meeting the 4 histological criteria for tonsil tissue as defined by Fioretti, is described in this report. A 68-year-old woman, in whom a mass in the hypopharynx had been found during endoscopic examination of the esophagus, was referred to our hospital. Endoscopic and X-ray examination revealed that the mass was located in the right postarytenoid region. Under general anesthesia, the tumor was extirpated by lateral pharyngotomy.
