 We studied the X-ray findings of undifferentiated type gastric carcinoma arising in gastric body and fundus to improve the ability to diagnose linitis plastica-type gastric carcinoma. All of 68 early gastric cancers were macroscopically depressed type and 37 lesions (54%) had ulcers or ulcer scars with fold convergence. Meanwhile among 26 lesions of type 4 advanced gastric cancers only 7 lesions (27%) had ulcers or ulcer scars with fold convergence and 12 lesions (46%) were located in the area of gastric fold. Therefore, detection of early cancer located in the area of gastric fold without fold convergence is important. These lesions were demonstrated by X-ray studies as furrowed shadow crossing the fold, interruption of the fold, or barium shadow between the folds. An undifferentiated type gastric carcinoma arising in gastric body may have an extensive infiltration in the gastric wall. Therefore, careful investigation of not only of the mucosal lesion but also the surrounded area are necessary. To detect the latent linitis plastica-type gastric carcinoma, it is important to take notice of the changes of mucosal folds and of the mucosal fine structures.
