Unusual endobronchial prostatic metastatic tumor occluding right main bronchus.

Endobronchial metastasis from extrapulmonary solid tumors is rare, and endobronchial metastasis from the prostate is even more unusual. An 80-year-old patient presented with significant dyspnea secondary to metastatic stromal cell sarcoma of the prostate, which occluded the right main bronchus. The tumor, causing complete collapse of the right lung, was found on computed tomography and confirmed by bronchoscopy. We successfully excised the lesion using cryotherapy, with immediate resolution of symptoms and radiological lung reexpansion.
