Bleeding in Hemophilia is more likely to involve which type of sites?

• A. Mucosal bleeding from gums
• B. Epistaxis with mild bleeding
• C. Easy bruising after minor trauma
• D. Deep tissue bleeding such as hemarthrosis, splenic hemorrhage or rectus sheath hematoma

Answer: (D)

Bleeding in hemophilia is driven by a deficiency in the coagulation cascade factors (usually factor VIII or IX), which impairs the formation and stabilization of the fibrin clot. Because secondary hemostasis is defective, bleeding tends to occur in deep tissues where clots form more slowly and are less stable. Joint spaces and muscles are classic sites, leading to hemarthroses and large muscle hematomas, and even retroperitoneal or abdominal wall bleeds can occur. Platelet function and mucosal surfaces are less affected, so superficial mucosal bleeding or easy bruising from minor trauma is less typical than deep tissue bleeds. Therefore deep tissue sites like joints and other muscles are most characteristic of hemophilia.
