We present the case of a 15-year old-girl who underwent transplantation for therapy-related myelodysplasia secondary to Ewing sarcoma treatment who developed pancytopenia with myelodysplasia 1 year after transplant due to copper deficiency. Copper deficiency is an important consideration in the evaluation of pancytopenia and myelodysplasia in pediatric patients. *Department of Pediatrics, Division of Pediatric Hematology/Oncology †College of Medicine ‡Department of Pathology, Medical University of South Carolina, Charleston, SC The authors declare no conflict of interest.
