[Small focal lesions of the stomach]

Small lesions of the stomach in 71 patients are examined roentgenologically, endoscopically and morphologically. The material of 110 gastrobiopsies and 17 stomachs removed because of carcinoma are also studied. The morphological characteristics of small focal stomach lesions (polyps, chronic ulcer, chronic erosions, chronic gastritis, carcinoma) which roentgenologically can be diagnosed only in 62%, is presented. The existing system of patient examination requires a new approach, i.e. the correct and duly diagnosis of stomach carcinoma is possible if repeated endoscopy and morphological study of biopsies are carried out. It seems that the group of "increased risk" should consist of patients with small focal lesions of the stomach in which pronounced dysplasia of the epithelium is observed histologically.
