Abstract

The article presents data on IgG4-associated disease. The disease has many different phenotypes, differing in epidemiological, serological data, prognostic outcomes, and effectiveness of therapy. The disease mimics a tumor, infectious and inflammatory disease. The presented clinical case of a 48-year-old patient confirms the difficulties of early diagnosis of the disease. Timely verification of the diagnosis of IgG4-associated disease is of important clinical and prognostic importance.

Keywords: Cholangitis, cholestasis, autoimmune pancreatitis, sclerosing cholangitis, fibrotic disease, Mikulich’s disease
