Abstract
Intraductal papillary neoplasm of the bile duct (IPNB) is a rare but recognized precursor to invasive carcinoma of the biliary tree and is characterized by dilated intrahepatic ducts with mucinous or papillary epithelium. Progression of papillary biliary neoplasia from benign disease to malignancy is thought to be similar to the pathway of an intraductal papillary neoplasm of the pancreas. The mainstay of therapy has been surgical resection. Surgical series demonstrate high rates of invasive cancer arising from IPNB; rates range from 40% to 70%.
