Epstein-Barr virus (EBV) lymphoproliferative disease (LPD) is a potentially fatal complication that may follow allogeneic hematopoietic stem-cell transplantation (HSCT). In this article, the authors report a 2-year-old girl with Hurler's syndrome who developed multiple central nervous system (CNS) EBV LPD lesions 1 year after unrelated donor HSCT. Before this CNS occurrence, the patient had a complete response to rituximab treatment for EBV LPD of the spleen and lymph nodes; however, treatment of the CNS disease with rituximab proved ineffective. Because of reported favorable response of primary CNS EBV LPD in two human immunodeficiency virus-positive patients, the authors treated this patient with low-dose oral hydroxyurea. The patient improved clinically, with a decrease in size of multiple EBV LPD brain lesions. Subsequently, the patient received EBV-specific cytotoxic T-cell lymphocytes and remains well. The benefit and limited toxicity of hydroxyurea therapy merit its further consideration as treatment for EBV LPD.
