Metastatic endometrial stromal sarcoma: A rare cause of right-sided intracardiac mass.

The endometrial stromal sarcoma (EES) is a rare uterine malignancy and its intracardiac metastasis are exceedingly rare. We report a case of a 53-year-old female patient diagnosed with a metastatic tumor of a ESS in the right side of the heart, who underwent successful surgical resection and initiated chemotherapy with docetaxel and gemcitabine. At a 9-month follow-up, the patient was in New York Heart Association-Class I, without any further complications.
