[Soft tissue necrotizing infection].

Necrotizing fasciitis and gas gangrene represent a rapidly progressive and fatal tissue infection in the absence of early multidisciplinary treatment. There are multiple risk factors, but diabetes remains the main one. The presence of crackles or extensive lesions are an indication for exploration and surgical treatment. Conservative management is associated with zero survival. Iconography, biology or bacteriology can help in the diagnosis, but the latter is only made during surgery. The associated mortality is high, despite appropriate management. We report here the case of a diabetic patient requiring insulin, having presented this pathology, the starting point of which is a traumatic wound, with an extensive acute course, contra-indicating any surgical procedure.
