Adenocarcinoma arising from ectopic gastric mucosa in the cervical esophagus.
Ectopic (heterotopic) gastric mucosa (EGM) of the upper esophagus, referred as inlet patch, is an asymptomatic benign lesion that is often detected during endoscopic examination. Although it is considered a source of adenocarcinoma in the upper esophagus, only 17 cases of adenocarcinoma have been reported previously. We report a rare case of adenocarcinoma arising in EGM of the cervical esophagus.
