Background

  • Much rarer than Necrotizing fasciitis
  • May be preceded by skin abrasions, blunt trauma, heavy exercise
  • Most patients are otherwise healthy (DM and other underlying conditions do not appear to increase risk)

Clinical Features

  • Exquisite pain and swelling of affected muscle with induration
  • Overlying skin changes may manifest later in the course of illness (erythema, warmth, petechiae, bullae)
  • Hypotensionmay occur rapidly with development of streptococcal toxic shock syndrome
