  • Abstract
  • Look Inside

 Early gastric cancer of type I having a peculiar gross shape associated with benign polyps was found in a 64-year-old female complaining of feeling of fullness in the upper abdomen. The cancer lesion located in the corpus looked at a first glance in x-ray examination like a submucosal tumor because the protruding lesion continuous with a mucosal fold appeared like a bridging fold. On further observation, however, an apparent border was recognized between the mucosal fold and the tumor so that the latter was regarded as a mucosal protrusion. Endoscopy revealed slight unevenness and discoloration on the surface of the elevation with partial erosion and bleeding. The diagnosis of protruding type of early cancer was thus arrived at. The other protuberance in the antrum was undoubtedly confirmed both by x-ray and endoscopy as a benign polyp. Gross as well as histological picture of the resected specimen showed a clublike protrusion measuring 53×10×5 mm in an area extending from the lesser curvature of the corpus away to the posterior wall. Adjacent to it, there was another elevation shaped like the letter V, measuring 30×22×5 mm, with its one end fused into a rnucosal fold running toward the posterior wall. Between the two protrusions was seen a thin groove-like boundary. The surface of the latter protrusion was granular with a distinct variance of hue between it and the continuing mucosal fold. Well differentiated adenocarcinoma tubulare with submucosalinfiltration was recognized in the area nearly corresponding with the extent of the two lesions. The other two protruding lesions in the antrum were both adenomatous polyps.

 Because of their peculiar shapes, two protrusions in the corpus should be diffentiated from non-epithelial tumor; they must be confirmed by biospy.
