Management of a Young Patient With High-risk Multiple Myeloma Complicated by Acquired von Willebrand Syndrome: A Diagnostic and Therapeutic Emergency

Abstract

Multiple myeloma associated with bleeding events secondary to von Willebrand syndrome is underdiagnosed. The management of this entity is highly complex, and aims to control the hemorrhagic syndrome and reduce plasma viscosity with plasmapheresis and multiple myeloma-specific treatment. The authors report the rare case of a young patient with high-risk multiple myeloma complicated by hyperviscosity syndrome and presenting an acquired von Willebrand syndrome with hemorrhagic manifestations, requiring urgent therapeutic management to save the patient's life.
