(en) [Rare manifestations of monoclonal gammopathies: About two clinical cases and literature review]. INTRODUCTION: Monoclonal gammopathies are common over the age of 50. Patients are usually asymptomatic. However, some patients present with secondary clinical manifestations, which are now grouped under the entity « Monoclonal Gammopathy of Clinical Significance » (MGCS). CASE REPORT: Here, we report two rare cases of MGCS: an acquired von Willebrand syndrome (AvWS) and an acquired angioedema (AAE). CONCLUSION: The discovery of a decrease in von Willebrand activity (vWF:RCo) or angioedema in a patient over 50 years of age, in the absence of a family history, should prompt a search for a hemopathy and in particular, a monoclonal gammopathy.
