FIG1
The patient had a recent computed tomography (CT) scan that showed a large obstructive endotracheal mass arising from the posterior tracheal wall with dimensions of 2.4 x 1.4 x 4.5 cm, approximately, with no evidence of lymph node metastases or locoregional invasion (Figure 1a, 1b).
(a) Intraoperative endoscopic visualization of the tumor after tracheotomy was performed. (b) Intraoperative endoscopic visualization, from tracheostomy, of tumor extension inside the tracheal lumen. (c) Endoscopic visualization of the carina after partial tumor debulking.

FIG2
Using a 45  rigid endoscope that was inserted from the tracheostomy, we managed to visualize all the tumors, which extended below the tracheostomy until a few cm above the carina (Figure 2a, 2b, 2c).
