Intracardiac metastasis originated from chondrosarcoma

Area of Science:

• Cardiology
• Oncology
• Pathology

Background:

• Primary cardiac tumors are rare; secondary (metastatic) heart tumors are more common, found in up to 20% of cancer deaths.
• Chondrosarcoma, a malignant skeletal tumor, typically metastasizes but cardiac involvement is exceptionally rare and undescribed in recent literature.

Observation:

• An 18-year-old male presented with systemic symptoms leading to the diagnosis of a right atrial mass.
• The mass was identified as a cardiac metastasis originating from a left scapular chondrosarcoma.

Findings:

• This case represents the first described instance of cardiac metastasis from chondrosarcoma in medical literature.
• Chondrosarcoma is characterized by rapid evolution, high metastatic potential, and poor response to chemotherapy, complicating patient management.

Implications:

• This case underscores the importance of considering rare metastatic sites in the differential diagnosis of cardiac masses, even in young patients.
• The complex management and differential diagnosis, particularly from infective lesions, are highlighted in this life-threatening condition.
