ABSTRACT

Heterotopic gastric mucosa located in the cervical esophagus is a congenital anomaly. Symptoms and morphologic changes are associated with the destruction of acid secreted by the heterotopic gastric mucosa. Malignant transformation and adenocarcinogenesis may also develop in these foci. In this case report we present a patient who initially could not be diagnosed despite two trials of upper gasrointestinal endoscopy, and however later diagnosed to have heterotopic gastric mucosa at cervical esophagus on intense investigation following his persistent complaints.
