[Pulmonary benign metastasizing leiomyoma from uterine myoma; report of a case]

A 46-year-old female with benign metastasizing leiomyoma was reported. The patient had undergone a lobectomy of thyroid for adenomatous goiter at the age of 30, and a myomectomy for uterine myoma and a modified radical masmectomy for breast cancer at the age of 32. The chest X-ray on health screening revealed multiple nodules in the bilateral lung. Computed tomography (CT) revealed 6 nodules in the right side and 3 nodules in the left side of the lung. The tumors of the right lung were resected under thoracoscopic surgery. Pathologically these lesions were diagnosed as benign metastasizing leiomyoma. Left lung nodules have been followed-up.
