Ectopic pancreas as a cause of upper gastrointestinal bleeding

Michal Vacík, Filip Shon, Miroslav Řežábek

Summary

Differentiated ectopic pancreatic tissue can develop anywhere in the gastrointestinal tract (GIT) and is most frequently found in the gastric or duodenal wall. Nowadays a development of ectopic pancreas stay unclear. The incidence of an ectopic pancreas is 0.55–13.70%, and such tissue is found more frequently in males than in females. Most ectopic pancreases are histologically categorized as type 1 according to Heinrich’s classification and contain all pancreatic components (acini, ducts, and endocrine cells). The majority of cases are asymptomatic; however, a large ectopic pancreas can cause various symptoms. Ectopic pancreatic tissue rarely causes bleeding. Here, we present two case reports. The first case was a middle-aged woman who developed anemia due to ectopic pancreatic tissue in the gastric wall. The second case exhibited acute bleeding due to a subpapillary lesion in the duodenum. Differential diagnosis can be difficult. Surgery and histological examination of the resected GIT led to a definitive diagnosis in both cases.
