Author contributions: Xie TH and Sun Q contributed to the drafting of the manuscript and revising the final draft; Fu Y, Ha SN, and Meng QX contributed to the acquisition of data and revising the final draft; Xie TH, Sun Q, and Wang P contributed to the investigation and interpretation of the data. All authors have read and approved the manuscript. Both Sun Q and Wang P played important and indispensable roles in the investigation, data interpretation, and manuscript preparation as the co-corresponding authors. Sun Q searched the literature, and revised and submitted the early version of the manuscript with the focus on the association between endobronchial metastasis and renal clear cell carcinoma. Wang P was instrumental and responsible for re-interpretation, a comprehensive literature search, and preparation and submission of the current version of the manuscript with a new focus on the mechanisms of endobronchial metastasis. This collaboration between Sun Q and Wang P was crucial for the publication of this manuscript and other manuscripts still in preparation.

Core Tip

Core Tip: Endobronchial metastases (EBMs) are tumours that metastasise from a malignant tumour outside the lungs to the central and subsegmental bronchi, and are visible under a bronchofibrescope. Renal clear cell carcinoma (RCCC) is a common malignant tumour of the urinary system. EBM from RCCC has a low complication rate and is often misdiagnosed as primary lung cancer. We report a case of post-operative EBM in a patient with RCCC who underwent laparoscopic radical nephrectomy 7 years ago. This suggested that if a bronchial tumour is found in a patient with RCCC, the possibility of EBM should be considered.
