In a febrile child with petechiae and ecchymosis, which diagnosis should be considered most concerning?

• A. Leukemia
• B. Hemorrhagic pancreatitis
• C. Neurofibromatosis
• D. Meningococcemia

Answer: (A)

Fever with petechiae and ecchymosis in a child points most urgently to meningococcemia. This pattern suggests meningococcal septicemia with rapid progression that can lead to disseminated intravascular coagulation, septic shock, and meningitis. It’s a medical emergency requiring immediate evaluation and empiric IV antibiotics plus supportive care. The petechial and ecchymotic rash reflects significant vascular involvement and coagulopathy, not just a benign platelet problem.

Leukemia can produce petechiae due to thrombocytopenia, but the combination of acute fever and a rapidly spreading purpuric/ecchymotic rash is more ominous for an acute septic process like meningococcemia. The other options don’t fit the presentation: hemorrhagic pancreatitis is uncommon in children and would typically bring abdominal symptoms, and neurofibromatosis is a chronic condition with skin and nerve lesions rather than an acute febrile purpuric illness.
