Abstract
Radiographic, endoscopic and pathological findings were correlated in 20 patients with polyploid esophagogastric lesions. In 16 patients, pathological examination showed chronic inflammatory change and epithelial hyperplasia; the polyp was located on the gastric side of the squamo-columnar junction, usually in association with a prominent gastric fold, and probably represented a localized form of gastritis. In the other 4 patients, the lesion was adenocarcinoma. An inflammatory esophagogastric polyp may be differentiated from polypoid carinoma when adequate radiographs are available and specific diagnostic criteria are followed. Endoscopic biopsy is recommended if the lesion does not fulfill the criteria of an inflammatory esophagogastric polyp.
