title: Serous cystadenoma of the esophagus.
abstract: A 77-year-old man found to have an esophageal polyp underwent polypectomy. Histopathological examination revealed that the polyp consisted of multiple microcystic structures similar to those observed in cystadenoma of the pancreas. This type of tumor is very rare in the esophagus, and is suggested to originate from esophageal glands or remnants from the embryonal state.
