What’s hidden under the gastric intestinal metaplasia? Diffuse-type adenocarcinoma dscovered by targeted biopsies: a case-report

Gastric corpus atrophy and intestinal metaplasia are two well established gastric precancerous conditions and scientific evidence shows a confidential relationship between this precancerous condition and intestinal type gastric cancer, according to Lauren classification. Differently, the background histological gastric mucosa characteristics from whom diffuse type gastric cancer may arise, need to be clarified. In this case, report we present a case of an 81-year-old female with corpus atrophic gastritis in whom we arrived at the diagnosis of diffuse type gastric cancer by following specific guidelines related to the characterization and the endoscopic-histological surveillance of gastric precancerous conditions.
