The clinical features and natural history of linear scleroderma in 53 patients and the laboratory tests helpful in the management of this disease are described. No patient had Raynaud's phenomenon or signs of systemic connective tissue disease in a mean follow-up of 10 years. Blood eosinophilia (> 300 cells/mm3) was present in half the patients, usually those with clinically active disease rather than inactive disease (p < 0.02). An elevated serum IgG level correlated with the presence of joint contractures (p < 0.02). Antinuclear antibodies, commoner in patients with extensive and prolonged disease, were present in 31% and 46% of patients whose sera were tested on mouse kidney and HEp-2 cells, respectively. Antibodies to single-stranded DNA, present in 50% of patients, were associated with extensive disease, joint contractures (p < 0.001), and active disease of greater than 2 years' duration (p < 0.001). Discordance in immune reactivity indicates that at least three serum autoantibodies exist in these patients: antibodies to single-stranded DNA and antinuclear antibodies with homogeneous and nucleolar immunofluorescence patterns.
