Scleroderma, which literally means "hard skin," is a painful and debilitating connective tissue disease characterized by excessive deposits of collagen in the skin. The hallmark of this disease is skin thickening, but scleroderma can also involve other organs such as the gastrointestinal tract, lungs, heart, or kidneys. The disease can begin at any age, but it usually affects people in their most productive years, and women more frequently than men.
