Core Tip
Core tip: We herein report a case of localized type 1 autoimmune pancreatitis (AIP) superimposed upon preexisting multifocal intraductal papillary mucinous neoplasms (IPMNs) of the branch duct. Although few reports have shown AIP associated with IPMN, in our case, AIP had developed only around the IPMN, which was under progressive observation. Therefore, the IPMN may have influenced the pathogenesis of AIP.
