Comparative clinicopathological study of biliary intraductal papillary neoplasms and papillary cholangiocarcinomas

Abstract

Given the significant contrast in clinicopathological features between IPNBs and papillary cholangiocarcinomas, it may be more appropriate to use the diagnostic term 'IPNB' for selected tumours that show regular papillary growth, separately from papillary cholangiocarcinomas.
