Abstract
A case of stomach carcinoma, which was difficult to make an accurate diagnosis because of its unusual macroscopic findings and very low cellular atypism, has been reported. A 50-year-old man was admitted to Osaka Medical School, because of his epigastric pain. A Borrmann type III stomach carcinoma, lymphosarcoma or reactive lymphoid hyperplasia were suspected by several series of barium meal and endoscopic examinations of the stomach which showed a shallow ulcerous lesion accompanying a low enbankment, but 19 biopsy specimens taken by three biopsy procedures revealed gastritis only (Group I & II). A tumorous lesion showing a low platteau like elevation with a shallow depression on the top and accompanying conversing folds. The size was 4.5 cm by 4.0 cm, the tint and the texture of the surfance were almost the same as the normal mucosa without mucous coat. It was found on the anterior wall of the resected stomach. Histologically, a greater part of the lesion showed extremely low cellular atypism to diagnose carcinoma, but the appearance of actual invasion to the surrounding tissue at the margin of the lesion and lymphatic invasion led us to make the diagnosis of carcinoma.
