[Hyperplastic polyp in heterotopic gastric mucosa. A rare lesion of the cervical esophagus]

Abstract

Patches of heterotopic gastric mucosa are often endoscopically detected in the upper third of the esophagus. A hyperplastic polyp developing on one of those heterotopic fundic mucous areas is a rare event. In this paper, a case revealed by pyrosis is reported in a 60-year-old man. Though there may be malignant potential, no malignant transformation of such a lesion has been reported so far in the esophagus.
