Scleroderma or systemic sclerosis is an auto-immune disease that causes scar tissue to form on the skin near the hands and face. As a result, the skin hardens and thickens. Scleroderma can also produce the same effects on internal organs and, in severe cases, affect vital organs like the heart and lungs. The condition is caused by an overproduction of collagen within the skin tissue as a result of the immune system attacking the body. The attack causes the body to produce healing agents in abundance, resulting in thickened patches of skin. There is currently no cure for scleroderma, but medications can be prescribed that manage pain and reduce the intensity of the immune system.
