Pulmonary benign metastasizing leiomyoma from the uterus in a postmenopausal woman: report of a case

摘要

Benign Metastatic Leiomyoma (BML) is a disease that stems from pulmonary smooth muscles and it is generally observed in multiple locations, including uterine leiomyomas. Apart from lungs it has been reported in lymph nodes, peritoneum, myocardium, eye, brain and spinal cord. We report a case of pulmonary BML from the uterus in a 50-year-old woman. Multiple nodules were identified in the lung fields by computed chest tomography of the patient, who presented with hemoptysis for 2 months. Endobronchial lesion was not observed by bronchoscopy. Cytopathological and immunocytochemical results confirmed the diagnosis of leiomyoma after the exploratory thoractomy. She had undergone hysterectomy with oophorectomy for uterine leiomyoma 5 years earlier, at the age of 45. Primary origin was from the uterus because hysterectomy and oophorectomy were performed 5 years ago for the leiomyoma. We present this case because it is a rare entity.
