People with scleroderma often develop lung disease called interstitial lung disease. This study will use ultrasound to detect shadows on the lungs called ?lung comets? among patients with scleroderma who have diagnosed lung disease, and those who have no evidence of lung disease. This is not a drug study. We are enrolling scleroderma patients to complete two visits over a period of approximately 12 months. Information about your medical history, exam findings, and laboratory tests will be collected for analysis. This study will involve approximately 40 participants.
