Purpura fulminans localising to a recent burn injury

The development of progressive, severe skin changes (purpura fulminans) is a serious complication of septicaemia, particularly meningococcal septicaemia. Purpura fulminans almost invariably leads to some full thickness skin loss and may lead to limb amputation. The pathophysiology may involve microemboli, endotoxins and direct bacterial damage to the vessels. We describe a case of purpura fulminans, probably as a result of meningococcal septicaemia, localising to a recent, healed burn with complete resolution. We can find no other record of the skin manifestations of meningococcal septicaemia localising to a previous injury.
