A case of necrotizing soft tissue infection of the posterior neck

A 43-year-old male patient presented with erythema and swelling in the right posterior neck, accompanied by purulent discharge and bleeding from a hair follicle, raising suspicion of necrotizing soft tissue infection (NSTI) .Extensive necrosis was observed from the epidermis to the muscle layer, and thorough debridement was performed, successfully controlling the local infection.To address the resultant skin defect in the posterior neck, reconstructive surgery was conducted using a rotational flap and split-thickness skin graft postoperatively.The patient was discharged without any subjective functional impairment.NSTI involving the posterior neck is rare, and we report this unusual case.Since the lesion was localized to the posterior neck and occipital region, aggressive debridement could be performed during the initial surgery, which was considered crucial for the patients survival.
