Abstract

Intraductal papillary neoplasms of the bile duct (IPNBs) are recognized as a distinct type of biliary tumor. We herein discuss the possible mechanisms underlying the development of multiple tumors in patients with IPNBs through a case presentation and literature review. A 64-year-old woman initially underwent extended right hepatectomy for IPNB in the right hepatic duct. Although the surgical margin of the common bile duct was tumor-free, recurrence was detected in the intrapancreatic bile duct 26 months later. Both tumors had similar histopathological characteristics (intestinal-type IPNB with high-grade dysplasia, but no invasive cancer). A literature review identified 9 additional cases of multiple IPNBs. Unlike conventional IPNBs, which typically affect the intrahepatic or hilar bile duct, 80% of recurrent multiple tumors developed in the extrahepatic bile duct. Although multicentric tumors have been suggested in such cases, the intrabiliary dissemination of tumor cells appears to be more likely, as the majority of recurrent tumors develop in more distal parts of the bile duct compared with the primary tumor.
