What is (are) Scleroderma ?
Scleroderma is an autoimmune disorder that involves changes in the skin, blood vessels, muscles, and internal organs. There are two main types: localized scleroderma, which affects only the skin; and systemic scleroderma, which affects the blood vessels and internal organs, as well as the skin. These two main types also have different sub-types. Localized scleroderma can be divided in: Linear scleroderma (en coup de sabre) Morphea (localized, generalized, guttata and deep). Systemic scleroderma is subdivided in: Diffuse cutaneous systemic sclerosis Limited cutaneous systemic sclerosis (which includes CREST syndrome) Limited Systemic Sclerosis (or systemic sclerosis sine scleroderm). There are also cases of environmentally-induced scleroderma and cases where scleroderma is part of other rheumatic disorders, like rheumatoid arthritis, lupus or Sjogren syndrome. The underlying cause of scleroderma is currently unknown; however, some scientists suspect that it may be related to a buildup of collagen in the skin and other organs due to an abnormal immune system response. There is no cure, but various treatments can relieve symptoms.
