Core tip: Intraductal papillary neoplasm of the bile duct (IPNB) is very rare in the United States. In this article, we reported the first IPNB patient we encountered. The patient is a 38-year-old female who is one of the youngest patients that have been reported. She was found to have intraductal papillary masses in the common hepatic duct and liver parenchyma. The diagnosis was IPNB, gastric subtype. In a search of PubMed database, we collected 354 IPNB patients from 22 articles and summarized the clinico-pathologic features including geographic distribution, age, gender, symptoms, location, microscopic subtypes, differential diagnosis, pathogenesis and therapeutic options.
