Unusual Late Presentation of Hemophilia A in an Active Duty U.S. Marine Following Open Shoulder Surgery

Hemophilia A is clotting disorder affecting 8:100,000 males in the United States. It is an X-linked recessive genetic disorder, although about one-third of cases occur spontaneously without known family history. Because of the risk of uncontrolled hemorrhage on the battlefield, hemophilia and other bleeding disorders exclude individuals from service in the U.S. military. We report a case of an active duty U.S. Marine whose underlying diagnosis of Hemophilia A was discovered and treated by a multidisciplinary team of orthopedic surgeons and hematologists following recurrent hematomas after open rotator cuff surgery. The patient gave informed consent for publication.
