Case presentation. As shown by this figure, a 27-year-old male was taken up for traffic accident for polytrauma and the patient was successfully treated with fluid replacement, broad-spectrum antibiotics, and debridement of necrotic tissue, followed by reconstructive surgery. Computed tomography (CT) scans showed necrotizing soft tissue infection of the abdomen and perineum (a). Necrotizing had also affected the soft tissues below the skin, causing stretching of abdominal wall down to the right hip area (b). On local examination, the skin around the abdominal incision site was edematous, indurate and large area of skin defect in situ (c and d). Under local anesthesia, serial surgical debridement and change of regular dressing were performed at last 3 times a week. When the patient was taken for surgical debridement (e), cover the wound defect with chitosan sponge dressing to remove exudates and to promote wound healing (f), the severe infection subsided with daily wound irrigation and fresh granulation tissue gradually formed (g). At 32th day, her condition was significantly improved (h) and scar tissue eventually formed after discharge (i)
