AIMS Biliary intraductal tubular neoplasms that are non-mucinous and negative for MUC5AC are called intraductal tubulopapillary neoplasm (ITPNs). Intraductal tubular neoplasms with mucinous cytoplasm and MUC5AC positivity also occur, and their nature remains unclear although some pathologists may classify these as "IPNBs of gastric type". This study aimed to elucidate genetic features of biliary intraductal tubular neoplasms. METHODS Six resected cases of biliary intraductal neoplasm with 70% tubular configuration were characterized by the clinicopathol
