Systemic sclerosis or systemic scleroderma is an autoimmune disease of the connective tissue. It is characterized by thickening of the skin caused by accumulation of collagen, and by injuries to the smallest arteries. There are two overlapping forms. Limited cutaneous scleroderma is limited to the skin on the face, hands and feet. Diffuse cutaneous scleroderma covers more of the skin, and is at risk of progressing to the visceral organs, including the kidneys, heart, lungs and gastrointestinal tract.
