Lung parenchyma is a common organ for metastases of extrathoracic tumors, but endobronchial metastasis is very rare. In this report, we present a case of endobronchial metastases from renal cell carcinoma (RCC), and this was managed by performing operative resection. A 63-year-old man presented with frequent dry cough; he had previously undergone left nephrectomy and postoperative chemotherapy for grade 2 RCC eight years ago. Computed tomography and bronchoscopy showed an endobronchial tumor from the left lower lobe bronchus to the second carina, and this mass was diagnosed as a necrotic tissue with chronic inflammation at biopsy. During the operation, the mass was revealed to be a metastatic renal cell carcinoma on the frozen section diagnosis and there was no mucosal invasion on the resection margin of the left lower lobe bronchus. We performed lobectomy of the left lower lobe with systemic dissection of the mediastinal lymph nodes. The final histopathologic diagnosis of the endobrochial mass was metastatic RCC and any mediastinal lymph node metastasis was not found. The patient was discharged on postoperative day 10 without any postoperative complications.
