[Intestinal metaplasia and fungus involvement in peptic and neoplastic lesions of the mucosa of the stomach].

260 ulcers and 128 cancers were found by means of stomach biopsies. Analyzing the coincidence of ulcer resp. cancer with intestinal metaplasia or fungus contamination about double the frequency of linkage to intestinal metaplasia (26% versus 15%) and likewise to fungus contamination (13% versus 7%) could be ascertained.--The figures in the combinations of cancer resp. ulcer with fungus infection and IM (4% cancer; 2% ulcers) were strikingly low. This is to be explained by an increased immunologic defense function of the intestinalised stomach mucosa.--Following demands of practice any neoplastic process with ulcerated fungi-contaminated lesion of stomach mucosa has to be safely excluded.
