Intraductal papillary mucinous neoplasms are tumors that grow within the pancreatic ducts (the pancreatic ducts are the "tubes" within the pancreas that are used to transport fluids to the bowel to help with digestion). A variant of bile duct carcinoma, intraductal papillary neoplasm of the bile duct (IPNB) is a rare disease mainly found in Eastern Asia which encompasses a spectrum of intraductal papillary growth occurring anywhere along the intrahepatic and/or extrahepatic biliary tree that carries a high potential for malignancy.

IPMN, an acronym for Intraductal Papillary Mucinous Neoplasm, is a cause of pancreatitis in which there is a transformation of the cells that line the pancreatic duct into premalignant cells —cells that display characteristics that may develop into pancreatic cancer— that produce mucous and block off the pancreatic duct.
