Fulminant purpuric rash.
We report on a fatal case of purpura fulminans caused by severe meningococcaemia. Despite early and aggressive treatment with the use of a specific algorithm and the maintenance of a stable haemodynamic status in the first hour since admission, purpura fulminans developed impressively over a few minutes. Necropsy showed microvascular thrombosis in the dermis but not in visceral organs, suggesting the diagnosis of meningococcal septic shock with purpura fulminans limited to the skin. Acquired deficiency of protein C, which exerts anticoagulant and antiinflammatory functions, is the central mechanism ultimately responsible for purpura fulminans. The disorder predicts a poor outcome of meningococcaemia and early and aggressive resuscitation is recommended in the emergency department with antibiotics, volume expansion, inotropic drugs, and protein C replacement. An attitude of scepticism is appropriate in the management of these patients even when early resuscitation is successful and haemodynamic parameters remain stable.
