Therapeutic phlebotomy is recommended for treating hereditary hemochromatosis. However, the procedure and its efficacy for children remain unclear. We describe a young female patient with ferroportin disease, which was confirmed from excess iron deposition within hepatocytes and by identifying a heterozygous variant p.Cys326Phe in SLC40A1. She had been followed without phlebotomy. Liver histology at age 13 years revealed iron deposition progression. Phlebotomy was initiated and her iron markers and imaging findings improved without severe adverse effects. Therapeutic phlebotomy for children is effective and well-tolerated and should be considered as early as possible after a hemochromatosis diagnosis.
