Purpura fulminans is a rare, rapidly progressive and often fatal form of acute disseminated intravascular coagulation (DIC). It is marked by intravascular coagulation leading to thrombotic occlusion of small and medium-sized vessels, skin necrosis, cardiovascular shock and multi-organ failure. It is a dermatological and haematological emergency.
