Background
- Much rarer than nec fasc
- 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)
- Hypotension may occur rapidly with development of streptococcal toxic shock syndrome
Differential Diagnosis
Workup
Management
- Same as necrotizing fasciitis
