In von Willebrand disease, mucosal bleeding most commonly presents as

Explanation:
Mucosal bleeding is a hallmark of von Willebrand disease because a deficiency or dysfunction of von Willebrand factor impairs platelet adhesion to damaged mucosal surfaces and also lowers factor VIII stability. The nose has rich, delicate mucosa that is frequently exposed to minor trauma, making epistaxis the most common bleeding presentation. The other options are not typical: hives and erythema are inflammatory skin findings, not related to this coagulation disorder, and splenomegaly is not a feature of von Willebrand disease.
