Comprehensive Diagnostic Criteria for IgG4-Related Disease
Although IgG4-related disease (IgG4-RD) is a novel and important disease entity characterized by elevated serum IgG4 concentration and tumefaction or tissue infiltration by IgG4-positive plasma cells, its clinical diagnostic criteria have not been fully established. Many patients with IgG4-RD have lesions in multiple organs, either synchronously or metachronously, and the pathological features of each organ differ. We established comprehensive diagnostic criteria for IgG4-RD for the practical use of specialists and nonspecialists.
