Abstract

Papillary tumors are the rarest form of cholangiocarcinoma, usually present as intraductal masses in the common bile duct (CBD), which cause obstructive jaundice early in the course of the disease. A 66-year-old female had jaundice for one month. Abdominal ultrasonography revealed a 2-cm-sized hypoechoic mass located in the distal CBD with upstream biliary tree dilatation. Computed tomography and magnetic resonance imaging suggested the possibility of extrahepatic cholangiocarcinoma. We performed endoscopic retrograde cholangiopancreatography with intraductal ultrasonography, revealing a papillary mass without definitive bile duct invasion located in the distal CBD. The patient underwent successful surgery and was diagnosed with stage T1N0M0 papillary adenocarcinoma. The patient is currently, one year after the surgery, under follow-up without recurrence.
