title: New onset of immunoglobulin G4-related disease in a patient with relapsing polychondritis.
abstract: Relapsing polychondritis (RP) is a rare systemic autoimmune disorder characterized by the episodic and progressive deterioration of cartilage inflammation. Approximately 30% patients with RP have concurrent disease. However, there have been no previous reports of RP complicated by immunoglobulin G4-related disease (IgG4-RD). Here we report the case of a 67-year-old male who developed IgG4-RD approximately 20 years after RP diagnosis. The association between IgG4-RD and RP remains unclear.
