Background. Acquired factor VIII (FVIII) deficiency or acquired hemophilia A (AHA) is very uncommon in children. Patients with AHA usually present with abnormal or unexpected bleeding which may be life-threatening. These patients usually have unexplained, prolonged, and isolated activated partial thromboplastin time (aPTT). Consequently, FVIII activity should be immediately evaluated. Bleeding prevention is important in patients with AHA.Case report. We present a case of a previously healthy 13-year-old female who presented with intramuscular hematoma, soft tissue hemorrhage, and epistaxis who was eventually diagnosed with AHA.Conclusion. To our knowledge, the present report is one of the few reported cases of an Asian patient that was diagnosed with acquired hemophilia A at a young age.
