F8 and autoimmune hemolytic anemia: Acquired hemophilia A (AHA) is a rare bleeding disorder caused by autoantibodies against factor VIII (FVIII).[1,2] AHA can be a cause of severe bleeding, resulting in high morbidity and mortality.[1] Most AHA is idiopathic and may be also associated with malignancy, autoimmune diseases, and medication.[2] Hematological malignancies, especially lymphoid malignancies, are known to be underlying causes of AHA[1]; however, thus far, there is no report of AHA associated with Epstein–Barr-virus-associated T/natural killer-cell lymphoproliferative disease (EBV-T/NK-LPD).
