Intravenous immunoglobulin contributes to the control of antimelanoma differentiation‐associated protein 5 antibody‐associated dermatomyositis with palmar violaceous macules/papules

Autoantibodies to melanoma differentiation‐associated protein 5 (MDA5) are associated with a subset of patients with dermatomyositis (DM) who have rapidly progressive interstitial lung disease (RP‐ILD) with poor prognosis. Intensive immunosuppressive therapy is initiated before irreversible lung damage can occur; however, there are few lines of evidence for the treatment of RP‐ILD. Here, we report three cases of anti‐MDA5 antibody‐associated DM...
