Necrotizing fasciitis in a patient with bullous pemphigoid treating with systemic steroid

Abstract Necrotizing fasciitis (NF) is a rarely seen, life-threatening soft tissue infection characterized by progressive necrosis of skin, subcutaneous tissues and fasciae. Herein, we present a case of NF in a patient with bullous pemphigoid. A 78-year-old female patient was admitted with the left leg pain, swelling, redness and blistering. Streptococcus pyogenes was isolated from the wound culture. In the skin biopsy and the left leg magnetic resonance imaging, signs of NF were observed. The diagnosis of NF was considered. Then, urgent surgical debridement was performed by the department of plastic surgery. While under treatment with intravenous antibiotics therapy, unfortunately the patient died of acute renal insufficiency.
