Severe Anemia in an Adolescent Male With Sickle Cell Trait: A Case ReportChapa-Rodriguez, Adrian MD; Dighe, Dipti MD; Giordano, Lisa MDJournal of Pediatric Hematology/Oncology: January 2015 - Volume 37 - Issue 1 - p e60–e62 doi: 10.1097/MPH.0000000000000233 Online Articles: Clinical and Laboratory Observations Abstract Author Information Abstract Background: Sickle cell trait is generally considered a benign condition. However, it has been associated with uncommon comorbidities such as painless gross hematuria secondary to renal papillary necrosis and renal medullary carcinoma. Observation: We present a 16-year-old African American boy with sickle cell trait and a recent history of prolonged gross hematuria due to renal papillary necrosis. The patient developed severe iron deficiency anemia and required transfusion support. Conclusions: Although renal papillary necrosis is well-described, it is uncommon in pediatrics and only rarely results in the need for transfusion.
