necrotizing fasciitis

necrotizing fasciitis and got the famous title of a "flesh-eating infection/bacteria"! Typically the infection enters the body through a break in the skin such as a cut or burn.
Unlike cellulitis, necrotizing fasciitis involves the deeper layers of tissue down to the deep fascia and it is caused by anaerobic bacteria or group A streptococci.
Clinical manifestations include fever with an area of erythema.
If not treated, the tissue begins to turn gray/black (seen on the top photo). It spreads quickly and aggressively from the primary  infected area and beyond and can result in amputation, shock, and death if not treated by a combination of surgical exploration and debridement (removing the dead tissue - bottom left photo) with IV antibiotics.
This patient had undergone a fasciotomy, a limb-saving procedure where the fascia was cut to relieve tension or pressure of the underlying tissue due to extensive necrosis.
