Metaplasia represents the process of transforming a well-differentiated adult tissue into another type of adult tissue. Pancreatic metaplasia of the gastric mucosa represents the process in which the normal mucosa of the stomach is replaced with pancreatic formations, which mimic the structure of pancreatic acini. We describe the case of a male patient aged 39 who was admitted for abdominal pain, vomiting, hematemesis, melena, pale teguments, intense perspiration and nausea. The patient underwent surgery for suturing a perforated duodenal ulcer five years prior to this episode (2002). A gastric ulcer complicated with superior digestive bleeding and a chronic duodenal ulcer complicated with partial stenosis and perivisceritis were found during surgery. Gastric wall fragments were harvested and underwent usual histological techniques and immunohistochemistry. We found an ulceration from the gastric mucosa to the submucosa, covered by fibrino-leukocytic detritus. In the mucosal chorion we found numerous round or oval shaped nested formations which occupied the lower two thirds of the chorion, to the muscularis mucosae. Some metaplasic acini contain cells variable in shape, color and immunophenotype. Surrounding the nested acini we found tubular formations, formed of cubic shaped cells, representing excretory canals which were continued by gastric glands or opened directly in the crypts of the gastric epithelium.
