Diagnostic and therapeutic approach to endobronchial metastases from extra-thoracic neoplasms: A report of three cases and brief review of literature.

Introduction: Endobronchial metastases (EBMs) are rare, with primary tumours predominantly of breast, renal, and colorectal origin. Bronchoscopy is the diagnostic gold standard, with histological confirmation through immunohistochemical study.

Cases: We presented three cases of EBMs, one secondary to colorectal cancer and two associated with renal tumours.
