Laboratory examination showed IgG kappa monoclonal immunoglobulinemia, weakly positive ANA: 1∶100, slightly lower IgA: 0.88g/L. The diagnosis of scleromyxedema complicated with IgG κ paraproteinemia was made. The patient was treated with hormones and methotrexate for 2 months and the skin lesions improved significantly.
