title: Solitary pulmonary metastasis from prostate sarcomatoid cancer.
abstract: BACKGROUND
  Pulmonary metastasis from prostate cancer is considered to be a late event, and patients can be treated with chemotherapy or hormonal manipulation. However, there has been only a few reports on surgical resection for pulmonary metastasis from prostate cancer.
  
  
  METHODS
  We present a surgical case of solitary pulmonary metastasis from prostate cancer. A 73-year-old man underwent pelvic evisceration for prostate cancer. Histopathological examination revealed a poorly differentiated adenocarcinoma with a sarcomatoid carcinoma component. During postoperative follow-up, chest computed tomography showed a nodular shadow in the lung, and thoracoscopic wedge resection of the lung was performed. Histopathological examination revealed a histological appearance similar to that of the prostate sarcomatoid carcinoma. This is the first reported case of solitary pulmonary metastasis from prostate sarcomatoid cancer.
  
  
  CONCLUSIONS
  Isolated pulmonary metastasis from prostate sarcomatoid cancer is extremely rare, but surgery could be the treatment of choice.
