Endobronchial metastasis from transitional cell carcinoma of the urinary bladder

Endobronchial metastasis of urinary bladder cancer is rare. A 71-year-old man presented with shortness of breath and cough. He was diagnosed with prostate adenocarcinoma and transitional cell carcinoma of the urinary bladder in the past. Bronchoscopy identified grape-like endotracheal lesions clustering over the distal tracheal wall obstructing 50% of the tracheal lumen and causing an almost complete obstruction of the left main bronchus. There was also extrinsic compression of the left main bronchus along with patchy nodular tumoral lesions involving the right main and the intermediate bronchial walls. Histologic examination of the lesions showed endobronchial metastasis from the bladder cancer. Bronchoscopy is a highly valuable method for evaluating the uncommon endobronchial metastases. Therapeutic bronchoscopy in such cases can contribute to improving quality of life and may impact the survival of the patient. Our patient survived for 5 months after a therapeutic bronchoscopy.
