DefinitionScleroderma is a rare disease of the connective tissue. It can cause the tissue in skin, joints, and internal organs to thicken and stiffen. There are 3 major forms of the disease:
- Localized scleroderma (can be morphea or linea)—Usually affects only the skin in isolated parts of the body. This form is less serious.
- Systemic sclerosis—Affects widespread areas of skin and/or internal organs, most often the lungs. Certain categories of this form of scleroderma are more serious and can be fatal
- Overlap syndrome—May involve features of scleroderma and features of other autoimmune syndromes
CausesOverproduction of collagen and other connective tissue proteins are the main features of scleroderma. It is not clear what causes this overproduction. Malfunction of the immune system may contribute to excess collagen production.
Risk FactorsScleroderma is more common in women. The morphea type of scleroderma usually affects people 20-40 years old. Linear scleroderma often occurs in children. Systemic scleroderma is more likely to occur in people aged 30-50 years old.Other factors that may increase your risk of developing scleroderma include:
- Family members with autoimmune disorders
- Occupational chemical exposure, such as silica, ketones, or welding fumes
Localized SclerodermaSymptoms are usually restricted to the skin. This disorder does not progress to involve internal organs. The skin lesions may completely reverse themselves in a few months or a few years. In some cases, they lead to permanent disfigurement. Symptoms include:
- Hard patches on the skin, most often on the face or trunk (morphea)
- Lines of plaques or thickened skin.
- Thickening can extend to underlying muscles and bones (linear scleroderma or linear morphea)
- Muscle and joint aches, and tiredness may occur with morphea
Systemic SclerodermaThis form of the disease is typically categorized as either limited or diffuse disease. Many cases of limited disease begin gradually with Raynaud's phenomenon. This involves swelling, tingling, numbness, blue and white color, and pain in fingers and toes. The fingers turn red after resolution of the symptoms. It is brought on by cold or emotional distress. The condition can progress over the years to thickened skin.
