[Helicobacter pylori infection and the risk of gastric carcinoma. Report of a case].

The authors present the clinical history of a patient with gastritis of the antrum who subsequently had early gastric cancer of the antrum. The authors review the literature on the infection by Helicobacter pylori as a risk factor for gastric carcinoma. The infection produces chronic gastritis, gastric ulcer, duodenal ulcer and is a probable risk factor for gastric carcinoma.
