ABSTRACT

Intraductal papillary neoplasm (IPN) of bile duct presents the tumor of a papillary surface comprising innumerable frondlike infolding of proliferation of columnar epithelial cells surroudings slender fibrovascular stalks. Neoplasm in the bile ducts which are dilated due to obstruction by a tumor itself, sloughed tumor debris, and excessive mucin. There are some researches of IPN of bile duct because they have same embryonic origin between IPN of bile duct and intraductal papillary mucinous neoplasm (IPMN) of pancreas. Patient with fever was suspected liver abscess in abdominal ultrasonography. Intraductal papillary neoplasm (IPN) of bile duct was suspected in additional imaging study. We experienced intraductal papillary neoplasm with high grade intraepithelial neoplasia after surgical resection. Here we report a case with the review of the reported literature.
