A 19-year-old man was admitted to the hospital with malaise, fatigue, and intermittent fever (temperature of 38°C [100.4°F]) for the last 2 weeks. Physical examination revealed scarce purpuric lesions over the lower extremities; a pericardial friction rub was audible over the precordium when the patient was supine and seated, and the spleen was remarkably enlarged.
