A testicular tumor metastasis formed a mass in the heart, causing tricuspid regurgitation. Despite surgical removal, the patient succumbed to lung bleeding from tumor infiltration.

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.
