BRUN, Solange et al. Von Willebrand disease acquired in multiple myeloma: case report. Rev. Urug. Med. Int. [online]. 2024, vol.9, e403.  Epub 01-Dic-2024. ISSN 2393-6797.  https://doi.org/10.26445/09.01.11.

Acquired von Willebrand disease (AVWS) is a rare acquired bleeding disorder with clinical and laboratory features similar to congenital von Willebrand disease. Associated with hemato-oncological, autoimmune, cardiovascular diseases and solid tumors. Monoclonal gammopathies constitute a heterogeneous group of disorders characterized by the proliferation of B lymphocytes in the last stages of maturation or plasma cells that preserve the capacity to produce a monoclonal immunoglobulin (Ig) or one of its components. As a consequence, the appearance of a paraprotein or M component (CM) occurs in serum and/or urine, which will be formed by the same heavy or light chain, and by identical variable regions. We present the case of a 57-year-old woman, who presented with a hemorrhagic parous syndrome, alteration of the crasis in its intrinsic way, where Acquired Von Willebrand Disease secondary to Multiple Myeloma is diagnosed. Treatment was aimed at stopping the bleeding, preventing complications, and promptly addressing the underlying hemato-oncological pathology. For its approach, it required the performance of therapeutic plasma exchanges that had a role of early and effective therapeutic action with excellent tolerance. Given the diagnosis, polychemotherapy was quickly started, this patient being a candidate for hematopoietic stem cell transplantation. The objective of presenting this clinical case is to highlight the importance of a correct and timely diagnosis in the face of clinical suspicion of a coagulopathy secondary to an underlying hemato-oncological disease. Therefore, we emphasize the multidisciplinary approach.
