Meningococcemia:

Fulminant Meningococcemia (Purpura Fulminans) is one of the most rapidly lethal form of septic shock in children. It differs from most other forms of septic shock by the prominence of hemorrhagic skin lesions (petechiae, purpura ) and the consistent development of DIC. Many times the CSF is clear. It presents as acute onset of purpuric rash in a child with fever. There may be signs of meningitis. Unless treated urgently with steroids and penicillin it is fatal.
