Primary leiomyoma: a rare space occupying lesion in the right ventricle

Abstract

A case of primary cardiac leiomyoma arising from the infundibulum of the right ventricle of a 24-year-old woman is presented. The mass protruded into the cavity of the right ventricle and caused severe right ventricular outflow tract obstruction. We resected the tumor under cardiopulmonary bypass successfully, and confirmed it histologically to be a benign leiomyoma. To the authors' knowledge, this is the first case report of a primary cardiac leiomyoma in an adult woman.
