Paroxysmal nocturnal hemoglobinuria with onset in childhood: a case report.
A twelve-year-old boy presented with recurrent episodes of anemia. Complete blood counts showed pancytopenia. Bone marrow was hypercellular with erythroid hyperplasia and depleted stores of iron. Positive Ham's test and sucrose lysis test revealed that he had paroxysmal nocturnal hemoglobinuria. There was a delay of nearly two years in the diagnosis in this patient. Paroxysmal nocturnal hemoglobinuria is rare in childhood. It must however be considered in a child who presents with unexplained anemia or bone marrow failure so that an early and accurate diagnosis is reached.
