Transverse image of cervical ultrasound from case 8. Note the degree of intraluminal invasion of the tumor and loss of airway patency. Arrows indicate residual tracheal lumen. Crosses demarcate boundaries of the tracheal wall

Cervical ultrasound showed circumferential involvement of the trachea with intraluminal invasion (Figure 1).
Gross histopathology of the tracheal tumor from case 8. Note the marked expansion of the tracheal wal and surrounding adventitia

Necropsy confirmed the presence of a circumferential tracheal mass with intraluminal invasion (Figure 2).
Neoplastic cells are replacing the mucosa (asterisk) and extending transmurally to expand the adventitia; islands of neoplastic cells are surrounded by a marked scirrhous response
