2. Figure 1
Computed tomographic images of the chest from patient with a glomus tumor. Axial view (left) and coronal (middle) and sagittal (right) reconstructions of the trachea show the endoluminal and extraluminal extent of the tumor.

3. Figure 2
Highly detailed and interactive virtual bronchoscopy can be performed by constructing a 3-dimensional model from very thin computed tomographic sections acquired on a multidetector scanner. This view of the trachea directed from the level of the thoracic inlet demonstrates the posterior lobulated glomus tumor, the degree of airway compromise, and the position of the tumor relative to the carina in the background.

5. Figure 4
Tracheal tumor consists of trabeculae and sheets of uniform cells surrounding dilated vascular channels of varying size (hematoxylin-eosin, original magnification ×40).

6. Figure 5
Immunoperoxidase stain demonstrates that the tumor cells are strongly positive for smooth muscle actin. Note the round, regular appearance of the nuclei (original magnification ×200).
