 The present study was retrospective and aimed to investigate the magnifying endoscopic appearance of early gastric cancer without H. pylori(Helicobacter pylori)infection from April 2005 to June 2018. We included 40 patients who fulfilled the requirement of not being infected by HP in the diagnosis as well as endoscopic and histological examinations. Of these, 21 patients had very well differentiated adenocarcinomas of the gastric phenotype, whereas 19 had signet-ring cell carcinomas. Fundic gland type adenocarcinomas and signet ring cell carcinomas did not exhibit demarcation lines because their surfaces were covered with the normal foveolar epithelium. In addition, some highly differentiated adenocarcinomas of other gastric phenotypes exhibited only subtle irregularities of surface patterns because of their pathological characteristics. However, we conclude that elaborate magnifying endoscopy could potentially estimate the histopathological structures of such gastric type adenocarcinomas by detecting the subtle surface and vascular abnormalities.
