Objective: Pancreatic heterotopia is a rare entity, which is commonly found in the stomach, duodenum, jejunum and Meckel's diverticulum. Heterotopic pancreas is extremely rare in the gallbladder. Despite being a congenital condition, it takes years to become symptomatic. It can be associated with cholecystitis or cholecystolithiasis. Method: A 21-year-old female patient was admitted to emergency service with abdominal pain. On physical examination, right upper abdomen was tender without defense or rebound. Abdominal ultrasonography revealed small sized gallstones and pericholecystic fluid. Magnetic resonance cholangiography showed dilated intrahepatic and extrahepatic bile ducts. Laparoscopic cholecystectomy was performed. Results: Cholecystectomy specimen was 75×35×30 mm. On gross examination we noted a few milimetric yellow colored stones and 12 mm yellow solid intramural nodule. The mucosa was covered with fibrinopurulent exudate. Microscopic examination revealed acute cholecystitis and aberrant pancreatic tissue consisting of acini and ductules. The phlegmonous inflammation of the gallbladder infiltrated the aberrant pancreatic tissue. The patient recovered completely after cholecystectomy. Conclusion: We found this case worth reporting because, pancreatic heterotopia of the gallbladder is a rare, clinically silent entity unless complicated with gallstones and acute cholecystitis.
