Primary cardiac synovial sarcoma

Area of Science:

• Cardiovascular Pathology
• Oncology
• Soft Tissue Tumors

Background:

• Synovial sarcoma typically affects extremities (90%) and constitutes 10% of soft tissue sarcomas.
• Primary cardiac malignancies are uncommon, with 25% of heart tumors being malignant.
• Primary synovial sarcoma of the heart is exceptionally rare.

Observation:

• A young patient presented with a rare primary synovial sarcoma originating in the right ventricle.
• Diagnosis required extensive investigations including histopathology, immunohistochemistry, electron microscopy, and molecular genetics.

Findings:

• The described case confirms the extreme rarity of primary cardiac synovial sarcoma.
• The tumor's aggressive nature was noted, with a generally poor prognosis.

Implications:

• Early and accurate diagnosis is crucial for managing this rare cardiac tumor.
• While often lethal, multimodal treatment including surgery and chemotherapy may offer survival benefits.
• This case contributes to understanding the clinical presentation and diagnostic workup of primary cardiac synovial sarcoma.
