Acute Ectopic Pancreatitis Mimicking Peptic Ulcer Disease: A Case Report.

Background: The ectopic pancreas is an anatomically separate pancreatic tissue from normal glands with its own vascular and ductal system; it is most commonly found in the upper gastrointestinal tract. The ectopic pancreas is usually asymptomatic, but it can present with symptoms associated with complications, including bleeding, inflammation, and neoplasm without abnormalities in the normal pancreas.

Case Presentation: We report a 31-year-old female with acute ectopic pancreatitis involving gastric antrum and proximal duodenum mimicking peptic ulcer disease, without pancreatitis in the normal pancreas.

Conclusion: Ectopic pancreatitis is a rare condition and can mimic more common diseases depending on the anatomical location.
