Immunoglobulin G4-associated cholangitis: one variant of immunoglobulin G4-related systemic disease.
IgG4-associated cholangitis (IAC) is a recently defined disease entity which shares a number of clinical, biochemical, and radiological features with primary sclerosing cholangitis (PSC). In contrast to PSC, IAC responds to immunosuppressive treatment, is not associated with inflammatory bowel disease, and mainly affects elderly men above the age of 60 years. Today, IAC is regarded as one varia...
متن کاملSerum Immunoglobulin G4 and Immunoglobulin G1 for Distinguishing Immunoglobulin G4-Associated Cholangitis From Primary Sclerosing Cholangitis
UNLABELLED The recent addition of immunoglobulin (Ig)G4-associated cholangitis (IAC), also called IgG4-related sclerosing cholangitis (IRSC), to the spectrum of chronic cholangiopathies has created the clinical need for reliable methods to discriminate between IAC and the more common cholestatic entities, primary (PSC) and secondary sclerosing cholangitis.

متن کاملImmunoglobulin G4-associated sclerosing cholangitis mimicking cholangiocarcinoma.
Immunoglobulin G4-related lymphoplasmacytic sclerosing disease is an emerging disease. Recently, it has been shown to be responsible for autoimmune pancreatitis-induced strictures of the bile duct mimicking cholangiocarcinoma. Making a diagnosis of immunoglobulin G4-associated sclerosing cholangitis requires a high index of suspicion. The differential diagnoses include primary sclerosing cholan...
متن کاملEsophageal Involvement of Immunoglobulin G4-Related Disease
Immunoglobulin G4 (IgG4)-related disease is characterized by the typical histopathological features of a dense lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells, a high ratio of IgG4- to IgG-positive cells, storiform fibrosis (cellular fibrosis organized in an irregular whorled pattern), obliterative phlebitis, and variable presence of eosinophils. The disease exhibits systemic in...
