Cardiac Plasmacytoma: A Rare Clinical Entity

Abstract

Primary malignant cardiac tumors are rare. Among these tumors, cardiac plasmacytoma is extremely rare and is the subject of few case reports. We present the case of a 73-year-old man who had isolated cardiac plasmacytoma 26 years after successful treatment of an axillary plasmacytoma. Multiple imaging methods—including echocardiography, cardiac magnetic resonance, and positron-emission tomography/computed tomography—were valuable and complementary to each other in this patient's diagnosis and optimal management. His case illustrates the use of these techniques in the successful diagnosis and treatment of a rare clinical entity, cardiac plasmacytoma.
