Benign metastasizing leiomyoma: a rare metastatic lesion in the right ventricle

Cardiac tumors require resection for diagnostic purposes and to avoid complications associated with an intracardiac mass. We present the case of a 41-year-old woman with a known uterine leiomyoma who presented 3 months after elective cesarian section and hysterectomy with a right ventricular mass that was confirmed histologically to be a benign leiomyoma of the same pathologic type as the uterine primary. Benign metastasizing leiomyoma is a rare pathologic entity occurring in women with a history of a uterine leiomyoma. This is the second reported case of cardiac metastasis from a benign uterine leiomyoma.
