RESUMEN
Paroxysmal cold hemoglobinuria is a rare autoimmune hemolytic anemia seen almost exclusively in children under 5 years of age after a viral illness. It is mediated by a biphasic polyclonal autoantibody against red blood cells, which causes severe hemolysis that typically self-resolves within 2 weeks without recurrence. While laboratory identification of the aforementioned antibody, the Donath Landsteiner antibody, would confirm this diagnosis, a negative test does not rule out this condition in the appropriate clinical context. We report on the rare occurrence of a severe presentation of paroxysmal cold hemoglobinuria in a 17-year-old male with Epstein-Barr virus infection.
