Abstract
Total 39 cases of carcinoma stomach were noticed out of 142 malignant tumours of GIT (27.46 percent). Histologically maximum cases were of diffuse type (56.41 percent) followed by intestinal type (35.89 percent) and indolent mucoid carcinoma (7.69 percent) of the stomach. The surrounding epithelium showed lot of changes in the intestinal type of carcinoma stomach. About 78.57 percent showed intestinal metaplasia, 14.28 percent of these cases showed chronic gastric ulcer and severe dysplasia (carcinoma in situ) and another 14.28 percent revealed villous adenoma with carcinoma in situ. In contrast to this, in diffuse variety, only 13.63 percent cases revealed intestinal metaplasia, 27.27 percent showed basal cell hyperplasia, stratification of the epithelium of crypts and diffuse infiltration of mucosa by malignant cells and 4.54 percent showed atrophic gastritis also. In mucoid carcinoma all cases had basal cell hyperplasia and stratification of crypts. Hence these conditions should be taken as premalignant lesions of stomach and should be cured in proper time.
