Multiple Primary Leiomyomas in the Right Ventricle: A Rare Form of Leiomyoma

摘要

A case of multiple benign leiomyomas in the right ventricle of a 47-year-old woman is presented. Multiple lesions were revealed at different locations in the right ventricle; 1 lesion extended into the right pulmonary artery. Histologic examination showed benign leiomyomas arising from the tunica media of the intramyocardial vessels. Also, the primary origin of the cardiac tumors is demonstrated by the evidence that no leiomyoma was found in the genital system 30 months after the cardiac operation. To our knowledge, this is the first case report of multiple primary cardiac leiomyomas in a premenopausal woman. The midterm prognosis after complete resection is good.
