Acquired von Willebrand syndrome is a rare bleeding disorder characterised by a later age of onset without a personal or family history of bleeding diathesis. It is vital to discern acquired von Willebrand syndrome from inherited von Willebrand disease and other acquired bleeding disorders as management differs significantly. Acquired von Willebrand syndrome is usually secondary to an underlying disorder such as lymphoproliferative disorder, myeloproliferative neoplasm, solid tumour, cardiovascular disorder, autoimmune disorders or hypothyroidism. Diagnosis is often delayed with a significant risk of morbidity and even mortality. Here we present a case of a 74-year-old man with an acquired bleeding disorder and work up suggestive of acquired von Willebrand syndrome secondary to immunoglobulin G kappa multiple myeloma. He was treated successfully with intravenous immunoglobulin, von Willebrand Factor/Coagulation Factor VIII Complex (human), myeloma directed chemotherapy and autologous stem cell transplantation. We also discuss the management strategies that are largely based on retrospective studies and case reports.
