Scleroderma is a connective tissue disease that involves changes in the skin, blood vessels, muscles, and internal organs. It is a type of autoimmune disorder, a condition that occurs when the immune system mistakenly attacks and destroys healthy body tissue.

Causes, incidence, and risk factors
The cause of scleroderma is unknown. People with this condition have a buildup of a substance called collagen in the skin and other organs. This buildup leads to the symptoms of the disease.
The disease usually affects people 30 to 50 years old. Women get scleroderma more often than men do. Some people with scleroderma have a history of being around silica dust and polyvinyl chloride, but most do not.
Widespread scleroderma can occur with other autoimmune diseases, including systemic lupus erythematosus and polymyositis. In such cases, the disorder is referred to as mixed connective disease.
Some types of scleroderma affect only the skin, while others affect the whole body.
- Localized scleroderma usually affects only the skin on the hands and face. It develops slowly, and rarely, if ever, spreads throughout the body or causes serious complications.
- Systemic scleroderma, or sclerosis, may affect large areas of skin and organs such as the heart, lungs, or kidneys. There are two main types of systemic scleroderma: Limited disease (CREST syndrome) and diffuse disease.
Skin symptoms of scleroderma may include:
- Fingers or toes that turn blue or white in response to hot and cold temperatures (See: Raynaud's phenomenon)
- Hair loss
- Skin hardness
- Skin that is abnormally dark or light
- Skin thickening, stiffness, and tightness of fingers, hands, and forearm
- Small white lumps beneath the skin, sometimes oozing a white substance that looks like toothpaste
- Sores (ulcers) on the fingertips or toes
- Tight and mask-like skin on the face
Bone and muscle symptoms may include:
- Joint pain
- Numbness and pain in the feet
- Pain, stiffness, and swelling of fingers and joints
- Wrist pain
Breathing problems may result from scarring in the lungs and can include:
Digestive tract problems may include:
Signs and tests
The health care provider will perform a physical exam. The exam may show hard, tight, thick skin.
Your blood pressure will be checked. Scleroderma can cause severe inflammation of small blood vessels, such as those in the kidneys. Problems with your kidneys can lead to high blood pressure.
Blood tests may include:
Other tests may include:
There is no specific treatment for scleroderma.
Your doctor will prescribe medicines and other treatments to control your symptoms and prevent complications.
Medicines used to treat scleroderma include:
- Power anti-inflammatory medicines called corticosteroids
- Immune-suppressing medications such as methotrexate and Cytoxan
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
Other treatments for specific symptoms may include:
- Medicines for heartburn or swallowing problems
- Blood pressure medications (particularly ACE inhibitors) for high blood pressure or kidney problems
- Light therapy to relieve skin thickening
- Medicines to improve breathing
- Medications to treat Raynaud's phenomenon
Treatment usually also involves physical therapy.

Some people with scleroderma have symptoms that develop quickly over the first few years and continue to get worse. However, in most patients, the disease slowly gets worse.
People who only have skin symptoms have a better outlook. Widespread (systemic) scleroderma can damage the heart, kidney, lungs, or GI tract, which may cause death.
Lung problems are the most common cause of death in patients with scleroderma.
The most common cause of death in people with scleroderma is scarring of the lungs, called pulmonary fibrosis.
Other complications of scleroderma include:
Calling your health care provider
Call for an appointment with your health care provider if:
- You have symptoms of scleroderma
- You have scleroderma and symptoms become worse or new symptoms develop
There is no known prevention. Reducing your exposure to silica dust and polyvinyl chloride may lower your risk for this disease.
