Treatment of relapsed multiple myeloma complicated by cardiac extramedullary plasmacytoma with D-PACE chemotherapy.

Cardiac extramedullary plasmacytomas (EMPs) are rare and may be a seen as a complication of multiple myeloma (MM) or in isolation. Here, we describe a case of cardiac EMP that presented clinically as a congestive heart failure exacerbation in a patient with relapsed and refractory IgG lambda MM. We highlight radiographic imaging in conjunction with laboratory biomarkers at presentation and in response to D-PACE (dexamethasone, cisplatin (Platinol), doxorubicin (Adriamycin), cyclophosphamide and etoposide) systemic chemotherapy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.
