Necrotizing soft tissue infection
Citation, DOI & article data
Necrotizing soft tissue infections are a category of bacterial infection characterized by rapidly progressive tissue destruction involving the skin, subcutaneous fat, deep fascia, and/or muscle.
Traditionally, such infections have been separated by the depth of involvement 1,2:
- necrotizing fasciitis, the most well known
- necrotizing myositis, including clostridial myonecrosis (gas gangrene)
- necrotizing cellulitis/adipositis
For several reasons, however, the overarching term of "necrotizing soft tissue infection" has been promoted. Involvement of adjacent levels can occur and, adding to the confusion, different authors and practitioners disagree on the definition of fascia 2,3. Moreover, the pathophysiology and clinical manifestations overlap. Most importantly, the management strategy for different necrotizing soft tissue infections is similar 1,4-6.
