title: Prostate adenocarcinoma metastatic to the lung.
abstract: Metastatic adenocarcinoma of the prostate must be considered in the differential diagnosis of any pulmonary nodule in an elderly man. Pulmonary metastasis is not uncommon, although chest films show evidence of disease in only about 5% of cases. Computed tomography may be beneficial as a cost-effective tool in staging adenocarcinoma of the prostate and in aiding in biopsy of the lesion. Fine-needle aspiration cytology of pulmonary nodules and immunoperoxidase staining techniques provide a specific diagnostic means of differentiating metastatic adenocarcinoma of the prostate from primary lung carcinoma and aid in proper staging and treatment. The authors presented the case of an 83-year-old man with prostate adenocarcinoma metastatic to the lung. Diagnosis was based on a chest film and lung biopsy findings. The patient was treated with bilateral orchiectomy.
