Scleroderma is a condition involving the abnormal growth of connective tissue that supports the skin and internal organs. For some people, hard, tight skin is the extent of this abnormal process. For others, the problem goes deeper, affecting blood vessels and internal organs. Although scientists do not know the exact cause of scleroderma, they are certain that people cannot catch it from or transmit it to others. Studies also show that scleroderma is not inherited. While there is no cure, treatment options are available to relieve symptoms and minimize damage.
