With the improvement in people’s awareness of diseases and the level of diagnosis and treatment, the incidence rates of immunoglobulin G4-related disease（IgG4-RD） and autoimmune liver disease（AILD） are constantly increasing, and IgG4-related sclerosing cholangitis is the overlapping part of the disease spectrum of IgG4-RD and AILD, while the association between IgG4-related autoimmune hepatitis（IgG4-AIH） and these two diseases remains unclear. This article reviews the hepatic manifestation of IgG4-RD, summarizes the clinical features of IgG4-AIH, and analyzes whether IgG4-AIH is a subtype of AIH or a hepatic involvement of IgG4-RD. It is believed that IgG4-AIH has similar but different clinical manifestations and histopathological features from classical AIH, and IgG4-AIH may be classified as two types, i.e., a subtype of AIH and the liver manifestation of IgG4-RD. The research on the pathogenesis, clinical features, and clinical diagnosis and treatment of IgG4-AIH should be taken seriously in future. [ABSTRACT FROM AUTHOR]
