Abstract
Purpura fulminans (PF) may be the presenting symptom in a patient with protein C (PC) deficiency. It is a hematological emergency and presents with extensive areas of hemorrhagic necrosis of the skin. PC deficiency is usually genetically inherited. However, we report a 1 year and 4 months boy, who presented with acquired PC deficiency possibly of postinfectious etiology and developed PF.
