Core Tip	IgG4-related sclerosing cholangitis (IgG4-RSC) is an emerging disease and shows frequent other-organ involvement, including of the pancreas. However, when isolation without pancreatic involvement and biliary mass formation are combined, IgG4-RSC becomes extremely rare and brings about a striking confusion in differentiation from cholangiocarcinoma. Avoiding unnecessary surgery and providing proper treatment in patients with isolated and mass-forming IgG4-RSC could be achieved through high index of suspicion according to the amount of information on the five cardinal features (histology, imaging, serology, other-organ involvement, and response to steroid therapy).
