Endobronchial Metastases after Radical Resection of a Primary Lung Cancer

Endotracheal/endobronchial metastasis （EEM） generally originates from nonpulmonary malignancies such as cancers of the breast, colon, and kidney. Although the incidence of EEM has been reported to be between 2.0% and 50.0%, cases diagnosed after radical resection of primary lung cancer are extremely rare. We hereby presented a patient of squamous cell lung carcinoma who was confirmed to have EEM 3 years alter his radical resection of primary tumor.
