Combined congenital defect involving both Factor VIII and XI is a very rare disorder. We describe a case of combined Factor VIII and XI deficiency in which the propositus has a mild hemophilia A and inherited a Factor XI deficiency from the father. Moreover, we report on the benefit of DDAVP administration to the patient during a bleeding episode.
