Key result
Surgical excision of a right atrial mass initially suspected to be a myxoma or hydatid cyst revealed a monophasic synovial sarcoma positive for TLE-1, BCL-2, and MIC-2.
Why the study?
Primary cardiac tumors are of rare presentation.
Case Report (n=1)
No
Highlights a rare presentation of primary cardiac synovial sarcoma in the right atrium, initially misdiagnosed as myxoma or hydatid cyst.
May warrant sarcoma consideration in atypical right atrial masses; leaves open optimal management strategies.
Primary cardiac tumors are of rare presentation. We present a case of primary cardiac synovial sarcoma of the right atrium admitted to our hospital. An initial diagnosis of right atrial myxoma or hydatid cyst was made based on echocardiographic and radiological features. Intraoperatively, an irregular mass was excised, and histopathologically, it was reported as monophasic synovial sarcoma. Immunohistochemistry was positive for TLE-1, BCL-2, and MIC-2.

Peesapati et al. (2022) conducted a case report in Primary cardiac synovial sarcoma with thrombocytopenia (n=1). Surgical excision was evaluated on Histopathological and immunohistochemical diagnosis. Surgical excision of a right atrial mass initially suspected to be a myxoma or hydatid cyst revealed a monophasic synovial sarcoma positive for TLE-1, BCL-2, and MIC-2.
