Introduction: Necrotizing fasciitis is a rare but potentially fatal soft tissue infection. It involves rapidly progressive necrosis of fascia and subcutaneous fat often with necrosis of the overlying skin. Patients may have systemic toxicity, characterized by altered mental status, malaise, leukocytosis, fever, chills, and pain. It most commonly involves the trunk, extremities and perineum. It is often associated with minor trauma, surgery, diabetes mellitus, or intravenous drug abuse. Mortality rate range is 20-40%. Early diagnosis and aggressive treatment are essential for preventing tissue loss and increasing survival.
