Hemolytic uremic syndrome followed by acute lymphocytic leukemia

A 4 6/12-year-old boy presented with severe hemolytic uremic syndrome (HUS) and then developed acute lymphocytic leukemia (ALL) 8 months later. Although other syndromes of hematopoietic dysfunction have been reported to precede the overt and classic findings of leukemia, this report describes a patient who developed ALL preceded by HUS, association not previously described.
