Abstract To the Editor:
IgG4-related sclerosing cholangitis (IgG4-SC) has recently been recognized as a biliary manifestation of IgG4-related disease (IgG4-RD). Type 3 IgG4-SC presented biliary strictures in both the porta hepatis and the distal common bile duct (CBD).[1, 2] Its manifestation, especially in the absence of autoimmune pancreatitis, is extremely rare and very similar to that of cholangiocarcinoma (CC).
