Hemoglobin sickle-hereditary persistence of fetal hemoglobin (S-HPFH) is a condition in which there is compound heterozygosity for the Hb S mutation and the HPFH deletion. These patients have no anemia, little evidence of hemolysis and generally have a benign clinical course compared to other types of sickle cell anemia. We describe a 19-year-old male with HbS-HPFH who had no history of anemia or vaso-occlusive crisis, who presented with a massive splenic infarct. We conclude that patients with HbS-HPFH can occasionally present with severe complications and require a high level of clinical suspicion for complications when presenting to the hospital.
