Key result
Surgical resection plus adjuvant chemotherapy achieves 2-year disease-free survival in right atrial synovial sarcoma.
Why the study?
Primary cardiac tumors are rare and synovial sarcoma of the heart is an uncommon diagnosis often initially mistaken for other masses.
Case Report (n=1)
No
Reports a rare case of primary cardiac synovial sarcoma mimicking a right atrial myxoma, successfully managed with surgery and adjuvant chemotherapy.
May inform management of rare cardiac sarcomas; leaves open standardized protocols pending prospective data.
Primary cardiac tumors are of rare presentation. We present a case of synovial sarcoma of the right atrium treated in our institution. An initial diagnosis of right atrial myxoma was made based on clinico-radiological features. Intra-operatively, an irregular mass was found. Histopathologically, it was reported as monophasic synovial sarcoma. Immunohistochemistry was positive for S-100, B-cell lymphoma-2, MIC-2 and calretinin. Patient received adjuvant chemotherapy and is currently free of disease for 2 years and on regular follow-up.

Eswaran et al. (2015) conducted a case report in Synovial sarcoma of the right atrium (n=1). Surgery and adjuvant chemotherapy was evaluated on Disease-free survival. Surgical resection and adjuvant chemotherapy for a right atrial synovial sarcoma resulted in the patient being disease-free at 2 years of follow-up.
