Abstract excerpt

The College of American Pathologists recognizes "intraductal papillary neoplasm of the bile ducts (IPNB) with an associated invasive carcinoma" in its protocols for the pancreas and intrahepatic bile ducts, but not for the perihilar or distal bile ducts. We aimed to investigate the clinicopathologic and molecular features of 27 surgically resected perihilar IPNB cases. The cohort included 14 males and 13 females,...
