Bleeding Diathesis in Multiple Myeloma: A Rare Presentation of a Dreadful Emergency With Management Nightmare.

Multiple myeloma is a neoplastic disorder of plasma cells. An abnormal coagulation profile, though commonly seen in multiple myeloma, can rarely manifest as life-threatening hemorrhagic complications. Bleeding tendencies in multiple myeloma can be explained by a variety of mechanisms such as dysfibrinogenemia, paraprotein-induced platelet dysfunction, shortened platelet survival, damage to the vascular endothelium, and acquired von-Willebrand syndrome. Herein, we report a 61-year-old female who presented with the signs and symptoms of hemorrhagic shock with multiple myeloma, which remained refractory to a massive transfusion protocol. Her condition stabilized when she was started on dexamethasone and antifibrinolytic infusion targeting acquired dysfibrinogenemia. To the best of our knowledge, hemorrhagic shock secondary to dysfibrinogenemia is an unusual phenomenon in multiple myeloma.
