Hamartoma of the bile duct. Report of a case

BACKGROUND: Gallstones and neoplasms generally cause obstructions in the biliary duct. There are some infrequent problems that may lead to obstructions, such as hamartomas of the biliary duct. Case report: A 34-year-old diabetic female patient begins with abdominal pain and jaundice. The diagnostic approach initiated with hepatobiliary ultrasound that reported cholelithiasis and enlargement of the biliary ducts. Cholangiopancreatography was subsequently performed and a biliary tree lesion was discovered; the patient underwent cholecystectomy with exploration of the biliary ducts. Clinical evolution was satisfactory. Pathologic findings indicated hamartoma of the biliary duct.
