In A, a chest CT scan with contrast enhancement showing a small lesion in the left lateral wall of the trachea (red arrow). In B, bronchoscopic images confirming the presence of a purple polypoid lesion in the left lateral wall of the lower third of the trachea; removal of the lesion (with forceps) resulted in significant hemorrhage, which was controlled with laser photocoagulation.

A chest CT scan with contrast enhancement revealed a newly forming lesion in the left lateral wall of the trachea (Figure 1A), with no other significant changes. Arfran S.A., Barcelona, Spain; Figure 1B). After the procedure, no additional complications resulting from the treatment were noted.
Histological examination of the lesion revealed numerous small vessels, some of which were capillaries, arranged in a lobular pattern and separated by a fibrous stroma with accompanying acute inflammatory changes, thus confirming the diagnosis of lobular capillary hemangioma. There were no signs of malignancy (H&E staining; magnification x100).
