title: Factor V inhibitor associated with immune complex formation.
abstract: A 72-year-old man was noted, shortly after surgery, to have a bleeding diathesis secondary to the development of a high-titer anti-factor V inhibitor. We documented the presence of factor V:anti-factor V IgG immune complexes and their disappearance following a short course of steroid therapy.
