title: [Pulmonary Benign Metastasizing Leiomyoma Resected Six Times during Twenty Years;Report of a Case].
abstract: Benign metastasizing leiomyoma (BML) is a rare condition in which a benign uterine leiomyoma causes metastasis, mainly to the lungs. The patient was a 72-year-old woman who had undergone hysterectomy for an uterine leiomyoma at 37 years of age. Between the ages of 52 and 68 years, she had undergone 5 metastatectomies for 10 BMLs. At the current presentation, 2 nodules located in the right upper lobe of the lung were resected. The histological diagnosis was BML, and immunohistochemical staining demonstrated that the tumor cells were positive for estrogen and progesterone receptors. Two years after surgery, the patient is alive without recurrence or respiratory symptoms. Multiple resections can be a treatment option for BML.
