Overview
            Scleroderma is a rare disease in which a person's immune system begins to change normal, healthy tissues. (This is called an autoimmune disease.) As a result, connective tissue of the skin, lungs, heart, and digestive tract is replaced with scar tissue. This change causes the tissues to become stiff and the muscles to not work as well.
