However there has been only a few reports on surgical resection for pulmonary metastasis from prostate cancer. Case Presentation 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. Conclusion Isolated pulmonary metastasis from prostate sarcomatoid cancer is extremely rare but surgery could be the treatment of choice. Background Although prostate cancer often metastasizes to the lung it usually metastasizes earlier to the bone 1 . Pulmonary metastasis from prostate cancer often shows a diffuse interstitial or multinodular pattern 2 . We report a rare surgical case of solitary pulmonary metastasis from prostate cancer. Case Presentation A 73-year-old man presented to the Department of Urology in our hospital with a chief complaint of nocturia. His past medical history was unremarkable. Pelvic computed tomography CT showed a large prostatic mass invading the rectum and bladder. The serum prostate-specific antigen PSA level was elevated to ng ml
