Diagnosis of congenital von Willebrand disease during a preoperative assessment in a multiple myeloma patient without bleeding history

Abstract

We report a rare case of type 2M von Willebrand disease diagnosed in an elderly multiple myeloma patient who had no personal and family bleeding history. This case report emphasis the importance to not systematically exclude a congenital vWD in adult patients when coagulation screening tests indicate toward a vWD.
