Abstract
Three cases of gastric lesion were examined and reported, in whom radiological, surgical and pathological findings were different one another before and after operation.
Case 1. 40-years-old man. The lesion was thought to be cicatrized ulcer at lesser curvature of antrum before operation, but exstirpated stomach showed small cancer invading into deep every layers and even subserosal tissue. Histologically it was composed of signet-ring cell carcinoma. Before operation it was suspicious for the existence of II-c type of early cancer in only one radiogram amomg fifteen pictures.
Case 2. 51-years-old man. A shadow-defect recognized at major curvature of gastric corpus, which was radiologically suspicious for a Borrmann's IV-type of cancer, revealed macroscopically and histologically an islet-like assemblance of giant mucosal rugae and non-cancerous lesions. The diagnosis was chronic gastritis hyperplastica circumscripta.
Case 3. 47-years-old female. It was cleared that the findings was the result of oppression to the stomach due to pancreatic hypertrophy and it's displacement, while radiological findings showed an infiltrative shadow defect at the posterior wall of gastric corpus and suspected for submucosal neoplasm before surgical operation.
