In locally advanced non-small-cell lung cancer (NSCLC), mediastinal staging is the cornerstone of the therapeutic decision and echoendoscopy is the most practiced exam to assess the lymph node involvement. We describe a rare case of endobronchial involvement by cells originating from a metastatic lymph node after endobronchial ultrasound (EBUS). A 64-year-old man was diagnosed with a squamous cell lung cancer with mediastinal nodal involvement proven by EBUS. The patient received neoadjuvant chemotherapy with partial response and was scheduled for a lobectomy. Before surgery, a fibroscopy was performed which demonstrated a 1-cm polypoid lesion settled on the internal face of the main right bronchus corresponding to the EBUS puncture site. The histological analysis confirmed tumoral cell in this lesion. The patient was rejected for surgery and undergo chemoradiation. This case highlights the need for a careful endoscopic control before surgical resection in case of prior positive EBUS followed by an interval of time.
