CREST syndrome Definition Scleroderma is a widespread connective tissue disease that involves changes in the skin, blood vessels, muscles, and internal organs. Alternative Names CREST syndrome; Progressive systemic sclerosis; Systemic sclerosis Causes The cause of scleroderma is unknown. Persons with this condition have a build up of a substance called collagen in the skin and other organs. This build up leads to the symptoms associated with the disease. The disease usually affects people 30 to 50 years old. Women are affected more often than men. Risk factors are occupational exposure to silica dust and polyvinyl chloride. Symptoms - Blanching, blueness, or redness of fingers and toes in response to heat and cold (Raynaud's phenomenon)
- Pain, stiffness, and swelling of fingers and joints

- Skin is hard
- Tight and mask-like facial skin

Treatment Drugs used to treat scleroderma include: - Nonsteroidal anti-inflammatory drugs (NSAIDs)
