Fifteen children with scleroderma have been presented. All had characteristic cutaneous abnormalities at onset and during the course of disease. All were girls. All had visceral involvement, primarily of the gastrointestinal tract, heart, and lungs. The presence of visceral disease might have been missed without specific and extensive diagnostic procedures, including gastrointestinal barium studies, esophageal motility, pulmonary function and carbon monoxide diffusing capacity, and plethysmography. Raynaud's phenomenon was frequent and accompanied by evidence of occlusive vascular disease. Contractures around joints were readily evident and arthralgias were common, but evidence of objective arthritis was absent. Sixty percent of the patients in this series had ANA. Overlap syndromes with myositis and SLE were present in 7 patients. Three of 15 children died 6-10 years after onset of disease.
