In recent years, the disease concept of intraductal papillary neoplasm of the bile duct (IPNB) has been attracting attention as a biliary lesion that is morphologically similar to intraductal papillary mucinous neoplasm (IPMN), which is considered to be a counterpart of IPMN. However, there are few reports on IPNB, and a consensus regarding the features of this disease is thus lacking. We experienced an extremely rare case of IPNB occurring in the bile duct at the duodenal papilla, which is a tumor presentation that has not previously been reported. Herein, we report this interesting case and discuss the possible association between IPMN and IPNB.
近年来，胆管内乳头状肿瘤（IPNB）作为一种在形态学上与导管内乳头状黏液性肿瘤（IPMN）相似的胆管病变，其疾病概念受到关注，IPMN被认为是IPNB的对应物。然而，关于IPNB的报道很少，因此缺乏对该疾病特征的共识。我们遇到了一例极为罕见的发生在十二指肠乳头胆管处的IPNB病例，这是一种此前未曾报道过的肿瘤表现形式。在此，我们报告这一有趣的病例，并讨论IPMN与IPNB之间可能的关联。
