title: Pulmonary benign metastasizing leiomyoma from the uterine leiomyoma: a case report.
abstract: BACKGROUND
  Benign metastasizing leiomyoma (BML) is a rare condition described as multiple well-differentiated leiomyomas at sites distant from the uterus. Apart from lungs it has also been reported in lymph nodes, heart, brain, bone, skin, eye and spinal cord. We present a case of pulmonary benign metastasizing leiomyoma in a female patient admitted to our hospital with suspicion of left adnexal tumor.
  
  
  METHODS
  A 45-year-old woman was referred to our hospital with suspicion of left adnexal tumor. The control transvaginal ultrasound examination performed at admission to the Gynecological Department excluded adnexal neoplasm. However, a large amount of fluid within the Douglas pouch raised the oncological concern. The patient underwent myomectomy in 2005. In the same year she was diagnosed with multiple lung nodules and underwent pulmonary wedge resection with the diagnosis of pulmonary benign metastasizing leiomyoma being stated. The decision of reevaluation of the specimen, control CT and puncture of the Douglas pouch fluid was made. Computed tomography performed at the Department of Diagnostic Imaging and Interventional Radiology of the Pomeranian Medical University Hospital revealed multiple, bilateral nodules. The microscopic examination of the samples confirmed the initial diagnosis of benign metastasizing leiomyoma with no evidence of neoplastic cells within the fluid.
  
  
  CONCLUSIONS
  Pulmonary benign metastasizing leiomyoma is a rare entity. However, it should be always taken into consideration in women with a previous or coincident history of uterine leiomyoma, especially when no evidence of other malignancy is present.
