Necrotizing fasciitis is a surgical emergency with a mortality of 100% if left untreated. It is a rare soft tissue infection that extends to the superficial fascia and rapidly progresses, often leading to septic shock. Laboratory values and imaging play a limited role as necrotizing fasciitis is a clinical diagnosis. Diagnosis is based on history and physical exam with characteristic skin findings such as pain out of proportion with pain extending beyond the induration, bullae, and crepitus. Management entails maintaining a high degree of clinical suspicion, aggressive fluid resuscitation, broad-spectrum antibiotics, and early surgical consultation. The definitive treatment is surgical debridement.
