Un tableau thrombo-hémorragique en rapport avec un syndrome hypoprothrombinémie - anticoagulant lupique révélant un myélome multiple à chaînes légères

Thrombosis and hemorrhage are two opposing manifestations of multiple myeloma. These hemostatic disorders are present in less than 12% of patients at diagnosis and involve various pathophysiological mechanisms. We report the case of a 39-year-old patient with multiple myeloma revealed by the association of a hemorrhagic syndrome and deep vein thrombosis related to a hypoprothrombinemia-anticoagulant lupus syndrome.
