title: Endobronchial metastasis from prostate cancer mimicking primary lung cancer.
abstract: Endobronchial metastasis from prostate cancer is a rare neoplasm which metastasizes to the proximal central or subsegmental bronchus, in a bronchoscopically visible range. We present a 72-year-old man with a left superior lobar bronchus mass, intrapulmonary metastases, and bone metastases, mimicking primary lung bronchogenic carcinoma. Increasing tPSA, decreasing fPSA/tPSA level, and prostatic puncture pathology proved prostate cancer. Pathomorphology and immunohistochemistry of the mucosa specimen with P504S, PSA revealed the diagnosis of pulmonary metastases from prostate cancer. The patient was treated by hormonal treatment and chemotherapy. He was in remission thirteen months after diagnosis.
