    1. Limited cutaneous Systemic Sclerosis (60% of cases)
      1. Typical skin involvement is distal to elbows and knees

        1. Telangiectasia
        2. Calcinosis cutis

        4. Digital ischemia
    2. Diffuse cutaneous Systemic Sclerosis (35% of cases)
      1. Skin involvement may be proximal to elbows and knees and may affect face
      2. Associated with Interstitial Lung Disease
      3. May present with renal disease

  6. Labs
    1. Antinuclear Antibody (especially nucleolar pattern)
      1. Present in 95% of Systemic Sclerosis (all subtypes)
    2. Anticentromere Antibody
      1. Most associated with limited cutaneous subtype (60-80% of cases)
    3. Antitopoisomerase-1 Antibody (Anti-Scl-70)
      1. Associated with diffuse cutaneous subtype (esp. more severe cases)
  7. Differential Diagnosis

Systemic Scleroderma (C0036421)

Definition (CHV) a rare, chronic disease characterized by excessive deposits of collagen in the skin or other organs

Definition (NCI_NCI-GLOSS) A disease that is marked by hardening and thickening of skin, connective tissue that surrounds other tissues and organs, and blood vessels.
Definition (NCI) A chronic disorder, possibly autoimmune, marked by excessive production of collagen which results in hardening and thickening of body tissues. The two types of systemic scleroderma, limited cutaneous and diffuse cutaneous are classified with focus on the extent of affected skin. A relationship exists between the extent of skin area affected and degree of internal organ/system involvement. Systemic scleroderma can manifest itself in pulmonary fibrosis, Raynaud's syndrome, digestive system telangiectasias, renal hypertension and/or pulmonary hypertension.
Definition (MSH) A chronic multi-system disorder of CONNECTIVE TISSUE. It is characterized by SCLEROSIS in the SKIN, the LUNGS, the HEART, the GASTROINTESTINAL TRACT, the KIDNEYS, and the MUSCULOSKELETAL SYSTEM. Other important features include diseased small BLOOD VESSELS and AUTOANTIBODIES. The disorder is named for its most prominent feature (hard skin), and classified into subsets by the extent of skin thickening: LIMITED SCLERODERMA and DIFFUSE SCLERODERMA.
Definition (CSP) systemic disorder of the connective tissue; manifested by hardening and thickening of the skin, by abnormalities involving the microvasculature and larger vessels, and by fibrotic degenerative changes in various body organs including the heart, lungs, kidneys, and gastrointestinal tract.
