title: Metastases from lung adenocarcinoma within a leiomyoma: A case report.
abstract: BACKGROUND
  Pulmonary adenocarcinoma rarely spreads to the gynecologic tract, and has not been fully reported to metastasize within a leiomyoma.
  
  
  METHODS
  A 47 year-old woman with recurrent pulmonary adenocarcinoma was incidentally found to have a positron emission tomography (PET) avid pelvic mass at the time of restaging. She was also noted to be anemic, and reported significant vaginal bleeding. She was taken for an uncomplicated hysterectomy. She was unexpectedly found to have adenocarcinoma within a leiomyoma, consistent with metastasis from her primary pulmonary adenocarcinoma.
  
  
  CONCLUSIONS
  We report one of the first cases of pulmonary adenocarcinoma metastatic to a uterine leiomyoma. A personal history of cancer should always be considered in patients presenting with symptomatic leiomyoma.
