Abstract

Factor X deficiency is a rare bleeding disorder that can be associated with life-threatening bleeding events. Factor X deficiency can either be inherited or acquired. Acquired cases of factor X deficiency can be seen in patients with plasma cell dyscrasias as well as amyloidosis. Coagulopathy, with clinically relevant bleeding events, although rare, is not an unusual phenomenon for patients with systemic amyloidosis. However, clinically relevant bleeding in patients with symptomatic multiple myeloma, without associated amyloidosis, has not been reported in literature before. We present a rare case of multiple myeloma without concomitant amyloidosis that presented with life-threatening bleeding from acquired deficiency of factor X and responded remarkably to treatment for underlying multiple myeloma. This case not only highlights the diagnostic workup required in patients with factor X deficiency but also provides the principles of management of acquired coagulopathy in plasma cell dyscrasias.
