 We retrospectively analyzed radiographic and endoscopic findings of patients with non-neoplastic gastric lesions which mimicked diffusely infiltrating gastric cancer. The patients were divided into three groups ; ulcerous rigidity (group A, 11 patients ; gastric syphilis, corrosive gastritis and partial splenic embolism-induced gastric damage), nonulcerous rigidity (group B, 5 patients ; tuberculosis peritonitis and chronic pancreatitis) and edematous lesion or lesion of thickened folds (group C, 15 patients ; acute gastritis and giant fold gastritis) . Group A, there were less extensive rigidity and significant mucosal damage. In group B, variable degrees of rigidity and obvious gastric folds were noted. In group C was characterized by less severe rigidity and less severe mucosal alterations. Comparing these groups with one another and with patients with diffusely infiltrating gastric cancer one or more differences in rigidity or in mucosal change or in pattern of gastric change were able to be identified. These finidngs suggest that the degree of rigidity, mucosal change and patterns of gastric folds are valuable in distinguishing diffusely infiltrating gastric cancer from nonneoplastic diffuse gastric pathology.
