Clinically, these episodes manifest as bleeding provoked by trauma, surgery, or invasive procedures, or spontaneously in moderate-to-severe disease Hemorrhages most commonly involve the musculoskeletal system—particularly recurrent intra-articular bleeding (hemarthrosis) and deep intramuscular hematomas—as well as mucocutaneous tissues or, less frequently, life-threatening intracranial and gastrointestinal sites
