Scleroderma

  • Alternative Names

    CREST syndrome; Limited scleroderma; Progressive systemic sclerosis; Systemic sclerosis; Localized scleroderma; Morphea, linear


    Symptoms

    Localized scleroderma usually affects only the skin on the hands and face. Its course is very slow, and it rarely, if ever, spreads throughout the body (becomes systemic) or causes serious complications.

    Systemic scleroderma is also called systemic sclerosis. This form of the disease may affect the organs of the body, large areas of the skin, or both. This form of scleroderma has two main types: limited and diffuse scleroderma.

    • Blanching, blueness, or redness of fingers and toes in response to heat and cold ( Raynaud's phenomenon)

    • 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
