Hilar cholangiocarcinoma associated with immunoglobulin G4‐positive plasma cells and elevated serum immunoglobulin G4 levels
Immunoglobulin G4 (IgG4)-related disease is a fibroinflammatory systemic disorder with multiorgan involvement. Proximal bile duct involvement results in IgG4-related sclerosing cholangitis, which is characterized by a lymphoplasmacytic infiltrate with abundant IgG4-positive plasma cells and fibrosis. Differentiating between cholangiocarcinoma and IgG4-sclerosing cholangitis can present a diagno...
متن کاملPathologic significance of immunoglobulin G4-positive plasma cells in extrahepatic cholangiocarcinoma.
Immunoglobulin G4-related sclerosing cholangitis is histologically characterized by the infiltration of immunoglobulin G4-positive plasma cells and sclerosing change. Moreover, several cases of carcinoma accompanied by immunoglobulin G4-positive cells in tissue and increased serum immunoglobulin G4 levels have been reported, but the association between cancer-associated immunity and an immunogl...
متن کاملPoor positive predictive value of serum immunoglobulin G4 concentrations in the diagnosis of immunoglobulin G4-related sclerosing disease
BACKGROUND Immunoglobulin G4 (IgG4)-related sclerosing disease is a recently described clinicopathological entity with diverse manifestations including, amongst others, autoimmune pancreatitis, sclerosing cholangitis, sclerosing sialadenitis and retroperitoneal fibrosis. Elevated serum IgG4 concentration has been described as the hallmark of this condition with reported good sensitivity and spe...

BACKGROUND Granuloma of the upper aerodigestive tract is a rare presentation of immunoglobulin-G4 (IgG4)-related disease. Since the disease process was defined in 2003, only 2 cases affecting the laryngopharynx have been reported in the literature. METHODS AND RESULTS A 62-year-old white man presented with persistent productive cough of brown sputum, globus symptoms, dysphagia, odynophagia, d...
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. The current American Association for t...
