A rare presentation of endobronchial metastasis from renal cell carcinoma resected 120 months after nephrectomy.

Introduction: Multipl extrapulmonary tumors can metastasize to the bronchus. Endobronchial Metastases (EBM) should be distinguished from these tumors because of their poor prognosis and different treatments. Case presentation: A 70-year-old male patient was admitted with thorax computed tomography, which was taken with the complaints of increasing cough and weight loss. The patient who had a history of left nephrectomy due to renal cell carcinoma 10 years ago did not have a history of receiving postoperative chemotherapy/radiotherapy. In bronchoscopy, the right lung upper lobe anterior subsegment entry was obliterated with an endobronchial lesion. The histopathological appearance was consistent with clear cell renal cell carcinoma metastasis Conclusion: This case is presented to emphasize that EBM may mimic primary lung cancers especially with respiratory symptoms. Ten years’ time interval is the longest period between radical nephrectomy and EBM in literature.
