PURPOSE: A 12-year-old girl developed severe autoimmune thrombocytopenia after a bone marrow transplant for acute lymphoblastic leukemia. RESULTS: Although epsilon-aminocaproic acid helped to control her bleeding, it eventually caused a rare myopathy previously undescribed in a pediatric patient. CONCLUSION: The myopathy resolved when the drug was discontinued and a different antifibrinolytic agent was used.
