Magnetic resonance imaging and computed tomography of the neck showed an enhancing polypoid mass of approximately 1.4 cm, causing partial obstruction in the right lateral wall of the trachea (Figure 1).
Tracheal mass biopsy with laryngeal microsurgery: (a) endoscopic view showing intratracheal mass, (b) endoscopic view showing the trachea after the biopsy of mass close to carina, and (c) the specimen of intratracheal mass.

Biopsy was performed by insertion of a suspension laryngoscope into the patient's mouth (Figure 2).
The tumor showed multilobular growth pattern with various histologic patterns, including cribriform (left side of the picture) and tubular (right side of the picture) pattern of adenoid cystic carcinoma (x200).

The frozen biopsy result indicated an adenoid cystic carcinoma (Figure 3).
Resection of tracheal tumor after sternotomy: (a) the reinforced tube was inserted through the open trachea in the surgical field, and the tracheal segment was being resected and (b) the specimen of resected tracheal segment of about 3 cm.

To maintain oxygenation, a reinforced sterile tube (ID 6.0) was inserted into the distal part of the trachea in the surgical field by a thoracic surgeon (Figure 4). The oral plain tube (ID 6.0) was withdrawn proximally about 2 cm to facilitate tracheal end-to-end anastomosis.
