A case of primary liposarcoma of the right atrium is presented. Liposarcomas of the heart are extremely uncommon, only 3 previous cases having been reported in the English-language literature. The tumour must be differentiated from other polypoid cardiac tumours, particularly cardiac myxomas.

A 61-year-old woman presented to our team with giant mediastinal liposarcoma causing compression of the esophagus, bronchus, and left atrium. Given the patient's advanced presentation and reduced cardiac reserve, rescue venoarterial extracorporeal membrane oxygenation was used in addition to standard robotic-assisted thoracic surgery for mass resection.

Article Synopsis
- Cardiac masses include various tumors, both primary and secondary, and often show non-specific symptoms, making early identification critical for aggressive types like sarcomas, which have a poor prognosis if metastatic.
- The report discusses two cases of patients with dyspnoea diagnosed with different sarcomas: one being a primary undifferentiated pleomorphic sarcoma and the other a secondary round cell myxoid liposarcoma, highlighting their distinct presentations and imaging findings.
- Undifferentiated pleomorphic sarcomas are the most common primary cardiac malignancy, typically arising in the left atrium, while round cell myxoid liposarcomas are rare metastases that can also affect the heart; both require prompt

The reported incidence of liposarcomas in ~2,000 cases annually results in about 30% of myxoid liposarcomas. Cardiac myoxid liposarcomas are very rare; their presentation could be cardiac tamponade, due to direct compression of the tumor and/or pericardial effusion. In this report, we describe a patient who presented with pericardial effusion secondary to myoxid liposarcomas from the right atrium, an extremely rare presentation of liposarcomas in the heart.
