Abstract

Gastric cancer without Helicobacter pylori infection accounts for less than 1% of all gastric cancers, and is generally considered to be less invasive. This report describes a rare case of H. pylori –uninfected gastric cancer with deep submucosal invasion and lymph node metastasis. Endoscopic submucosal dissection was performed, and pathological examination revealed tubular adenocarcinoma with deep submucosal invasion. We diagnosed foveolar-type gastric adenocarcinoma. While many cases of foveolar-type gastric adenocarcinoma, especially of the white elevated type, are reported as early stage gastric cancer, this case is very rare because it showed submucosal invasion and lymph node metastasis.
