"Necrotizing Fascitis is characterized by fulminant, extensive soft tissue necrosis, systemic toxicity, and high mortality. Early in the course, the disease can appear deceptively benign and may look like cellulitis.
Prompt diagnosis of necrotising fasciitis (NF) and early intervention reduces mortality and amputation rates. Unfortunately NF is misdiagnosed in the initial stages of the disease in almost 75% of the patients. Because thrombosis of large numbers of capillary beds must occur before skin findings develop, early infection has little overlying skin changes to indicate the extent of infection."
