Which finding is most characteristic of hemophilia?

• A. Easy bruising without mucosal bleeding
• B. Significant menorrhagia in females
• C. Mucosal or gingival bleeding
• D. Frequent epistaxis that resolves quickly

Answer: (C)

Hemophilia is a deficiency of a coagulation factor (factor VIII or IX) that impairs secondary hemostasis, so clot formation is slow and bleeds tend to be prolonged, especially after injury to deeper tissues or mucosal surfaces. Mucosal or gingival bleeding fits this pattern because even minor trauma to these surfaces requires a robust fibrin clot to stop oozing; without enough clotting factor, the bleeding at mucosal sites can be persistent. In contrast, significant menorrhagia in females can occur but is less characteristic of classic hemophilia since affected individuals are typically male, and epistaxis that stops quickly would be less expected with a coagulation-factor defect. Easy bruising without mucosal bleeding suggests a platelet-related issue more than a coagulation-factor deficiency. Therefore, mucosal or gingival bleeding best reflects the bleeding tendency seen in hemophilia among these options.
