Benign metastasizing leiomyoma of the lung: report of a case.Gen Thorac Cardiovasc Surg. 2013 Dec; 61(12):719-22.GT
A 35-year-old female presented with multiple bilateral pulmonary nodules on a chest X-ray during a regular health checkup. Chest computed tomography revealed multiple well-defined nodular shadows in the lung. She had undergone a myomectomy 7 years previously for leiomyoma of the uterus. Thoracoscopic resection of one of the nodules was performed to establish a pathological diagnosis. Pathological findings were consistent with benign metastasizing leiomyoma. Estrogen and progesterone receptors showed strong positives by immunohistostaining of the tumor. The patient is currently receiving outpatient treatment for a benign metastasizing leiomyoma by administration of a GnRH analog drug.
