[Early gastric carcinoma. Clinicopathological analysis of 50 cases (author's transl)].

50 cases of early gastric carcinomas have been diagnosed in the past 7.5 years (1973 - June, 1980). The clinical pathological aspects of these cases are presented. Grossly, the depressed lesions (IIc, IIc + III), and histologically, the differentiated carcinoma composed the majority and accounted for 60% and 64% respectively. There were only 7 female patients in this series, and 5 were signet ring cell carcinomas. All 7 signet ring cell carcinomas (5 female, 2 males) were confined to the mucosal layer, although the largest one reached 4.5 X 3.4 cm. A small intestinal type early gastric carcinoma (1.2 X 0.8 cm), developing from severe atrophic gastritis was found after repeated follow-up examinations by gastroscopy in a three year period.U
