Abstract
IgG4-related sclerosing disease is a novel clinical disease entity characterized by an elevated serum IgG4 concentration and tissue infiltration by IgG4-positive plasma cells. Although this disease is a novel entity, it is not rare and is present in a proportion of patients with a wide variety of diseases, including autoimmune pancreatitis, sclerosing cholangitis, retroperitoneal fibrosis, and inflammatory pseudotumor. Despite the effectiveness of steroid therapy, IgG4-related sclerosing disease is often misdiagnosed as a malignant tumor. Here, we report an inflammatory pseudotumor of the great omentum that was misdiagnosed as a malignant tumor and subject to surgical resection.
