Bronchogenic cysts are rare congenital anomalies that are formed due to abnormal budding of the endodermal foregut during embryogenesis. These cysts are found at various sites because the location of the cyst depends on the embryological state of the abnormal budding. Submucosal tumors (SMTs) of the esophagus that originate from the submucosa or the intramural layer account for less than 1% of all esophageal neoplasms, and bronchial cysts of the esophagus usually present as a type of SMT or as external compression. We report here on an interesting case of bronchogenic cyst presenting with dysphagia in an adult. (Korean J Gastrointest Endosc 2009;39:154-157)
