  • Definition
  1. Erythroderma (Exfoliative Dermatitis)
    1. Serious to life-threatening dermatosis with generalized skin erythema and Scaling
  • Epidemiology
  1. Age over 50 years old most common
  • Pathophysiology
  1. Generalized cutaneous vasodilation with inflammatory cell leakage into Dermis
  2. Generalized Edema and inflammation ensues
  3. Scaling follows inflammation after 5 days
  • Symptoms
  1. Diffuse Pruritus
  2. Constitutional symptoms (generalized weakness, malaise, chills)
  • Signs
  1. Ill or toxic appearance
  2. Diffuse, generalized bright erythematous skin (typically including palms and soles)
  3. Diffuse Scaling of skin (within 5 days of onset)
  4. Onycholysis
  5. Alopecia
  • Causes
  1. Preexisting dermatosis in 50% of cases (typically more gradual onset)
    1. Eczema
    2. Psoriasis
    3. Seborrheic Dermatitis
    4. Pityriasis rubra pilaris
    5. Ichthyosis
    6. Lichen Planus
  2. Drug Reaction (rapid onset)
    1. See Life-Threatening Drug-Induced Rashes
    2. See Fixed Drug Eruption
    3. Most common causes
      1. Antibiotics
      2. Seizure medications
      3. Cardiac medications
  3. Infection
    1. HIV Infection
    2. Toxic Shock Syndrome
    3. Norwegian crusted Scabies
  4. Leukemia or Lymphoma
    1. Cutaneous T-Cell Lymphoma (esp. stage 4, Mycosis Fungoides)
  • Management
  1. Hospitalize all patients with suspected Erythroderma
  2. Treat underlying cause if identified (e.g. Toxic Shock Syndrome)
  3. Manage complications
    1. Dehydration
    2. Electrolyte replacement
    3. Secondary infections
  4. Skin care - layered approach
    1. Layer 1: Low to moderate potency Corticosteroid (e.g. triamcinolone)
    2. Layer 2: Moist wrap or clothes
    3. Layer 3: Dry layer
  • Complications
  1. Dehydration
  2. Metabolic abnormalities
  3. High output Heart Failure
  4. Secondary Skin Infections
