  • Superficial epidermal infection characterized by amber crusts (nonbullous) or vesicles (bullous)
  • May be super-infection or primary infection
  • Fever and systemic signs are uncommon

Diagnosis

  • Nonbullous
    • Erythematous macules/papules develop into vesicles which become pustular and rupture
      • As rupture release yellow fluid which dries to form stratified golden crust
  • Bullous
    • Bullae form as result of staph toxin
    • Some cases caused by MRSA

Treatment

  • Topical abx
    • Mupirocin ointment 2% TID x 7-14d
  • Oral abx
    • Consider for large areas or if topical tx is impractical or for bullous impetigo
    • Clindamycin 24mg/kg/d in 3 doses x7-10d
