[Floating intracardiac metastasis]

Area of Science:

• Oncology
• Cardiology
• Pathology

Background:

• Testicular tumors can metastasize to distant organs.
• Cardiac involvement by testicular tumor metastasis is rare.

Observation:

• A 26-year-old man presented with cardiac murmur and lung metastases 2 years post-testicular tumor removal.
• Echocardiography revealed a mobile cardiac mass near the tricuspid valve.
• Elevated human chorionic gonadotrophin (hCG) levels indicated persistent tumor activity.

Findings:

• Surgical removal of the cardiac mass identified it as a testicular tumor metastasis.
• The mass caused tricuspid regurgitation and posed a risk of pulmonary outflow tract obstruction.
• Histological examination confirmed trophoblast-containing metastases in the lungs.

Implications:

• This case highlights the potential for late cardiac metastasis from testicular tumors.
• Early detection and management of cardiac masses in patients with a history of testicular cancer are crucial.
• Trophoblastic elements in metastases can lead to severe complications like pulmonary hemorrhage.
