Rigid bronchoscopy showed fibrotic net with tracts crossing the anterior-to-posterior trachea and causing a tracheal stenosis 5 cm below the vocal cords (Figures 1A,B, 2). Endobronchial laser therapy (Dornier Medilas Fibertom 8100, Nd- YAG laser) was applied on the fibrotic tracts achieving a good airway patency (Figure 1C). After 2 months follow-up, the patient showed significant improvement of respiratory symptoms and flexible bronchoscopy confirmed the lack of significative obstruction of tracheal lumen (Figure 1D).

This result was confirmed even 2 years after the treatment: a further flexible bronchoscopy demonstrated an optimal tracheal patency (Figure 3).
