Necrotizing fasciitis.

Necrotizing fasciitis is a synergistic infection caused by aerobic and anaerobic organisms, resulting in liquefaction and necrosis of the fascia. Clinical findings typically include septicemia, anemia and radiographic evidence of gas in the soft tissue. Most patients have a history of diabetes or atherosclerosis. Morbidity and mortality can be reduced by early diagnosis, extensive surgical debridement and aggressive nutritional support.
