 We examined the accuracy of macroscopic findings to diagnose the depth of invasion in esophagogastric junction adenocarcinoma using photographs of resected specimens obtained from endoscopic submucosal dissection or surgery. Based on the findings suggesting submucosal invasion in gastric cancer, the specificity of diagnosing submucosal invasion deeper than 500μm was high, but the sensitivity was low. A protruded lesion with a “table-like” appearance is characteristic of esophagogastric junction carcinoma with submucosal invasion. Histologically, lesions showed mucinous carcinoma or solid tumor growth. In addition, the depressed lesions were rarely accompanied by ulcerations. A “recessed marginal ridge” and a “nodular lesion in the depression” were additional findings of esophagogastric junction adenocarcinoma.
