Circulating anticoagulants in the form of acquired factor VIII inhibitors have typically been identified as immunoglobulin (Ig)G proteins. However, in a patient presented with a 2-year history of arthralgia and Raynaud's phenomenon, a factor VIII inhibitor was found associated with the serum macroglobulins. The patient was initially hospitalized for a herniorrhaphy, and detailed preoperative coagulation studies were completely normal. Postoperatively, the patient developed a pulmonary embolism, and anticoagulation therapy was initiated. The patient exhibited a marked sensitivity to warfarin. After this drug had been withdrawn, coagulation studies continued to demonstrate a clotting defect, and a specific factor VIII inhibitor was
