Solitary pulmonary metastasis from prostate sarcomatoid cancer

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. 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.
