Necrotising fasciitis usually involves the formation of bullae (thin walled blisters), ulceration of the skin and black scabs. We describe two pancytopenic patients with polymicrobial gram-negative bacteremia and fulminating gangrenous cellulitis. It's sometimes called the "flesh-eating disease", although the bacteria that cause it do not "eat" flesh, but release toxins that damage nearby tissue. Several processes, each with distinctive clinical features and microbiologic findings, may cause gangrenous cellulits: (Table V). this ppt highlights causes, microbiology and treatment of the condition.

The laboratory risk indicator for necrotizing fasciitis score can be helpful for distinguishing between cases of cellulitis, which should respond to medical management alone, and NSTI, which requires operative debridement in addition to antimicrobial therapy. NSTIs include necrotizing forms of fasciitis, myositis, and cellulitis. Symptoms appear usually within 24 hours of a minor injury. In necrotizing fasciitis, the visible findings on the skin are the tip of the iceberg. Can occur in extremities, trunk, perineum (Fournier's Gangrene), or head and neck.

Even with treatment, up to 1 in 3 people with necrotizing fasciitis die from the infection. . Upon entering the body, it rapidly reproduces and emits toxins/enzymes that damage fascia and soft tissue. The infection typically travels along the fascial plane, which has a poor blood supply. 1 doctor agrees. n Anaerobic and facultative bacteria work synergistically n Saltwater NF - variant minor skin wound is Cellulitis.
