Acquired Von Willebrand Syndrome following a SARS-CoV2 Infection

Acquired von Willebrand syndrome is a rare clinical entity with approximately 700 cases described in the literature. Different etiologies can be responsible for the occurrence of this condition, including mainly lymphoproliferative and myeloproliferative syndromes, as well as cardiac diseases. Several mechanisms have been implicated depending on the etiology. Viral infections are an extremely rare cause, with only one case reported after an Epstein-Barr virus infection. In this case report, we have described the very likely association between SARS-CoV2 infection and the development of a time-limited acquired von Willebrand syndrome.
