Cardiac plasmacytoma: a rare clinical entity

Area of Science:

• Cardiology
• Oncology
• Medical Imaging

Background:

• Primary malignant cardiac tumors are rare occurrences.
• Cardiac plasmacytoma is an extremely rare subtype, with limited case reports available.
• This case involves a patient with a history of treated axillary plasmacytoma.

Observation:

• A 73-year-old man presented with isolated cardiac plasmacytoma.
• The cardiac tumor was diagnosed 26 years after successful treatment of an unrelated axillary plasmacytoma.
• The patient's condition was managed using multiple complementary imaging modalities.

Findings:

• Echocardiography, cardiac magnetic resonance (CMR), and positron-emission tomography/computed tomography (PET/CT) were crucial for diagnosis.
• These imaging methods provided valuable and complementary information for patient management.
• The successful diagnosis and treatment of cardiac plasmacytoma were achieved.

Implications:

• This case underscores the importance of advanced imaging in diagnosing rare cardiac tumors.
• It demonstrates the successful application of multimodal imaging in managing cardiac plasmacytoma.
• The findings contribute to the understanding and clinical approach to rare cardiac malignancies.
