[Polymyositis/scleroderma autoantibody-positive scleroderma with dermatomyositis (scleromyositis)]

Polymiositis/scleroderma autoantibody positive scleroderma with dermatomyositis connected to interstitial lung fibrosis is reported. The recently observed overlap syndrome is characterised by the presence of special autoantibodies, HLA-type association and benign course. A new skin symptom (mechanic's hands) is described which may indicate the syndrome and one of its important internal manifestations, the interstitial lung disease.
