A Hypopharyngeal Ductal Cyst Masquerading as a Laryngopharyngeal Reflux Disease

Abstract

The ductal cyst of the hypopharynx is a very rare tumor. We report a case of hypopharyngeal ductal cyst in a 63-year-old man presenting with globus sensation. It was removed by a laryngomicrosurgical technique, using a microdissection electrode. Masses of the hypopharynx may not always be easily visible on routine examination of the hypopharynx with flexible fiberoptic laryngoscopes. Particularly in cases of benign tumors, the diagnosis may be delayed due to a prolonged history of mild and subtle symptoms. We missed the hypopharyngeal mass at the initial presentation, but could detect the mass in the pyriform sinus with a double contrast barium swallow study. We describe the diagnostic method to detect hypopharyngeal tumors and the treatment of benign hypopharyngeal masses.
