title: Anemia secondary to valproic acid therapy in a 13-year-old boy: a case report.
abstract: BACKGROUND
  Valproic acid is a commonly used anti-epileptic drug. Hematological toxicities are among the occasionally observed adverse effects of this medication.
  
  
  METHODS
  We present the case of a 13-year-old Caucasian boy who demonstrated mild anemia 12 months after the introduction of valproic acid therapy. A bone marrow biopsy revealed maturation arrest of proerythroblasts.
  
  
  CONCLUSIONS
  Prompt diagnosis and valproic acid discontinuation resulted in the patient's recovery.
