A febrile patient with pink papules on the upper chest and trunk, along with petechiae and ecchymosis, may indicate which condition?

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

Answer: (A)

The main idea is that skin bleeding with fever points to a problem with platelet function or production. In leukemia, the marrow is crowded with malignant cells, reducing megakaryocytes and causing thrombocytopenia. That leads to spontaneous petechiae and ecchymoses, often seen on the trunk and proximal surfaces, and fever can accompany infection or the leukemia itself. Pink papules can reflect small-vessel bleeding or cutaneous involvement from the disease, so this combination of fever with trunk-predominant petechiae and bruising fits leukemia best. Meningococcemia can also feature fever and a petechial/purpuric rash, but it typically presents as an acutely ill patient with rapidly evolving, often purpuric lesions and signs of sepsis or meningitis. Hemorrhagic pancreatitis would show abdominal findings and flank ecchymoses, not a trunk-wide papular rash. Neurofibromatosis presents with characteristic pigmented skin lesions and nodules, not an acute febrile rash with bleeding.
