Barrett Esophagus
Most esophageal adenocarcinomas arise from Barrett esophagus. Barrett esophagus is replacement of normal squamous epithelium of the distal esophagus with metaplastic columnar epithelium during the healing phase of acute esophagitis. In this image, red-appearing bands of metaplastic epithelium can be seen extending proximally.
