The purpose of this study is to examine fibrosis (excessive scar tissue formation) and inflammation in the lungs of patients with scleroderma and control subjects. Scleroderma is an autoimmune connective tissue disease characterized by skin, lung, and other organ fibrosis. The goal of this study is to gain more information about scleroderma to potentially aid in the development of potential new treatments. For this study we are recruiting the healthy control subjects (not having scleroderma and other autoimmune diseases, smocking no more then 1 pack cigarettes/day. The donors who will be participating in this trial will be asked to give a blood sample by blood draw and possibly skin sample through a skin punch.
