Abstract
Non-Hodgkin's lymphoma involving the tracheobronchial tree is uncommon. A 60-year-old man presented with severe cough for two months. Bronchoscopy disclosed an ulcerative lesion at the lower trachea and carina with anterior tracheomediastinal fistula, and biopsy revealed tracheal wall B-cell lymphoma. After chemo-radiotherapy, the tracheomediastinal fistula healed, but eight months later, tracheal stenosis was diagnosed by bronchoscopy. A self-expansible metallic stent was placed, which successfully maintained the airway.
