A 60-year-old man diagnosed with osteoarthritis of the right hip was referred to the authors' outpatient clinic for surgical intervention. Laboratory test results revealed elevated C-reactive protein and serum IgG levels. A subsequent laboratory test revealed an IgG4 level of 318 mg\/dL. Magnetic resonance imaging revealed an abnormal mass in the right hip joint. The authors suspected IgG4-RD of the hip. The mass was resected during total hip arthroplasty. Immunohistochemical analysis for IgG revealed positive staining of many plasma cells. Most of the IgG-positive plasma cells were positive for IgG4, and the ratio of IgG4\/IgG-positive cells was 51%. This case met all criteria for IgG4-RD; thus, the authors made a definitive diagnosis of IgG4-RD of the hip. The C-reactive protein level decreased to a negative value, and the IgG level decreased to a normal range at 3 weeks postoperatively. The IgG4 level gradually decreased to 152 mg\/dL at 5 months postoperatively. This is the first reported case of IgG4-RD of the hip joint.
