Removal of an underlying tumour may produce some improvement of the muscle weakness in adult dermatomyositis, though this is often only temporary.

Treatment options include:

  • glucocorticoids with or without second-line immunosuppressive agents including methotrexate, azathioprine, mycophenolate mofetil, and, in refractory cases, IVIG (intravenous immunoglobulin) or rituximab
