| Abstract: | We found a small gastric cancer in a 25‐year‐old woman with nodular gastritis. Endoscopically, the cancer was identified as a whitish area in the gastric antrum. There was also a miliary pattern in the gastric antrum and corpus. In addition, serology and histology revealed the patient to have been infected by Helicobacter pylori. Histological examination of the resected stomach showed that the cancer was poorly differentiated adenocarcinoma with signet‐ring cell restricted to the mucosal layer. In the surrounding mucosa, there were chronic inflammatory cell infiltrates and enlarged lymphoid follicles with germinal centers. Our case suggests that nodular gastritis may be at a high risk for the development of gastric cancer of poorly differentiated type. |
