A Case of von Willebrand’s Disease Diagnosed by Refractory Tonsillar Hemorrhage with a Family History

The disease termed von Willebrand’s disease (vWD) is an autosomal-dominant hereditary bleeding disorder caused by dysfunction or deficiency of the clotting factor called von Willebrand factor (vWF); vWF is produced by the vascular endothelial cells and bone marrow megakaryocytes, and plays a major role in platelet adhesion and aggregation in the processes of primary hemostasis.
