Key result
Resection of RV metastatic Ewing sarcoma achieves normal biventricular function and no recurrence at one year.
Case Report (n=1)
Surgical resection of a right ventricular metastatic Ewing sarcoma resulted in normal biventricular function and no recurrence at one year.
Single-case success suggests surgical feasibility for rare right ventricular metastases; leaves open need for larger studies on outcomes.
Ewing sarcoma is the second most prevalent malignant primary bone tumor but constitutes only a small proportion of cardiac metastases. We present a case of asymptomatic Ewing sarcoma metastatic to the right ventricle. A 36-year-old man presented for evaluation and resection of a pedunculated right ventricular cardiac tumor. Three years before, he had been diagnosed with translocation-negative Ewing sarcoma, for which he had undergone chemotherapy and amputation of the left leg below the knee. We resected the right ventricular tumor. Analysis of the resected mass supported the diagnosis of metastatic Ewing sarcoma. Postoperative transthoracic echocardiograms showed normal biventricular size and function. One year later, the patient had no recurrence of the sarcoma. In addition to discussing this case, we review the relevant medical literature.

Petrović et al. (2016) conducted a case report in Ewing sarcoma metastatic to the right ventricle (n=1). Resection of right ventricular tumor was evaluated on Recurrence of sarcoma. Resection of a metastatic Ewing sarcoma in the right ventricle of a 36-year-old man resulted in normal biventricular function and no recurrence at one year.
