Two patients with adenofibromyomatous hyperplasia located at the distal end of the extrahepatic bile duct are reported herein. The chief symptom in both patients was upper abdominal pain and the lesions found involved the proliferation of submucosal mucous glands and fibrous elements. Further progress in imaging diagnostic techniques would increase the frequency with which such lesions are discovered. But, even now, if mural irregularities and shadow defects are found in the extrahepatic bile duct, particularly in the distal end of the common bile duct, the possibility of a benign lesion such as adenofibromyomatous hyperplasia should be taken into consideration when making a diagnosis.
