Hemophilia A (classic hemophilia) is an hereditary coagulation disorder characterized by the absence, severe deficiency, or defective functioning of plasma coagulation factor VIII. It is inherited in an X-linked recessive manner and occurs almost exclusively in males. The first manifestations of bleeding are usually first noted as a young child since most of the patients with hemophilia A have a profound deficiency of factor VIII (less than 1% of normal value). However, in mild hemophilia (5-25% of normal level of factor VIII) the condition may escape detection with many of the patients developing bleeding only after trauma or surgery. Hemophilia A is the result of a recent genetic mutation in approximately one third of patients, for whom often there is no family history of a bleeding disorder. Here we present an elderly male patient with spontaneous bleeding in an extremity that has coagulation studies consistent with the diagnosis of hemophilia A. Physicians must be aware that mild hemophilia can present in this unusual manner and should consider this possibility in patients that have unexplained bleeding even if there is no clear personal or family history of an hereditary coagulation disorder.
