Pulmonary benign metastasizing leiomyoma: Report of three cases

Abstract

Benign metastasizing leiomyoma is very rare and usually occurs in women who undergo hysterectomy and myomectomy for uterine leiomyoma. This is a benign spindle-shaped smooth muscle cell tumor pathologically but metastasizes to the extrauterine organs. Lungs are the most common site of metastasis. We observed three cases of pulmonary benign metastasizing leiomyoma. © 2013 Jeon et al.; licensee BioMed Central Ltd.
