Endobronchial metastasis from renal cell carcinoma: a case report

A 46-year-old man had primary pulmonary symptoms of intermittent fever, cough and dyspnoea. Radiological investigations revealed a mass at right hilum with right upper lobe collapse. Bronchoscopy showed a luminal mass of which the biopsy showed a tumour with predominantly clear cell change. Subsequent investigations revealed primary renal adenocarcinoma. The differential diagnosis of clear cell lung tumour is discussed. This case of endobronchial metastasis from renal cell carcinoma is being presented because of its rarity.
