 Totally 26 cases of adenocarcinoma of the lower esophagus and EGJ(esophagogastric junction), limited to the mucosa or submucosa, were examined. There were no significant differences in pathologic characteristics among three groups of esophageal adenocarcinoma, adenocarcinoma of the esophagogastric junction, and adenocarcinoma of the proximal stomach. However, the existences of a poorly differentiated component, 0-IIb component, and atypical glands with indefinite for neoplasia were relatively frequent in the lesions with greater length in the Barrett's esophagus. Although adenocarcinomas of the lower esophagus and esophagogastric junction have been found under the common condition of gastroesophageal reflux disease, they may be divided into two groups such as adenocarcinoma with and without preceding Barrett's mucosa. For the latter group, Barrett's esophagus may be a paracancerous condition rather than a precancerous lesion.
