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)
- Hypotension may occur rapidly with development of streptococcal toxic shock syndrome
Differential Diagnosis
Skin and Soft Tissue Infection
- Cellulitis
- Erysipelas
- Lymphangitis
- Folliculitis
- Hidradenitis suppurativa
- Skin abscess
- Necrotizing soft tissue infections
- Mycobacterium marinum
Look-A-Likes
- Sporotrichosis
- Osteomyelitis
- Deep venous thrombosis
- Pyomyositis
- Purple glove syndrome
- Tuberculosis (tuberculous inflammation of the skin)
Diagnostic Evaluation
Management
- Same as Necrotizing Fasciitis
Disposition
- Admit/OR
