SclerodermaView All Arthritis Types
The name scleroderma is derived from the Greek word skleros, which means hard, and derma, which means skin. The most characteristic feature of scleroderma is the build-up of tough scar-like fibrous tissue in the skin. The disease may affect the skin alone (localized scleroderma) or be a systemic disease that involves internal organs.
The disease is classified as localized scleroderma, limited scleroderma and diffuse scleroderma. Localized scleroderma affects the skin and does not involve internal organs; other names for this condition include morphea and linear scleroderma. Systemic sclerosis is sometimes used to refer to the limited and diffuse forms of the disease.
The degree of skin involvement separates limited from diffuse scleroderma. People with limited scleroderma have skin thickening of their limbs but skin on their trunk and above the elbows and knees is spared. Those with diffuse disease have skin involvement of their proximal arms and legs and their trunk.View All Arthritis Types
