Abstract

Leiomyoma of the uterus is the most common benign uterine tumor affecting 40-50% of women older than 40 years of age. The pathogenesis of uterine leiomyoma is unknown, but several studies have suggested that each leiomyoma arises from a single neoplastic cell within the smooth muscle of the myometrium. Uterine leiomyoma can be extended outside the uterus growing into the pelvic veins, and in exceptional cases, even into the lung. Even if this was first reported more than 90 years ago, the pathogenesis and treatment of benign metastasizing leiomyoma was not still established. We experienced a case of benign metastasizing leiomyoma and report with a brief review of literature.

Key Words: Benign metastasizing leiomyoma
