Necrotizing fascitis induced by mosquito bite

Necrotizing fascitis usually occurs after a perforating trauma or sometimes surgery. It is an acute necrotizing process which involves the fascia of the skin. Within one or two days of the causative event the patient experiences pain, oedema and a dusky bluish-red discolouration of the skin with or without bullae formation. These areas become gangrenous usually by the fifth day. Often any specific organisms are not grown on culture, but the common ones that are include beta-haemolytic streptococci, coliforms, enterococci, pseudomonas. Treatment comprises early detection, surgical debridement, intravenous antibiotics and supportive care. We report a case of grossly neglected necrotizing fascitis caused by mosquito bites. Our treatment consisted of intravenous antibiotics, thorough debridement, regular dressings and a split-thickness skin graft. These measures collectively preserved an otherwise hopelessly mutilated upper limb.
