Although the usual morphology is usually “in cluster”, this unique and sessile papilloma, identical in color to the mucosa, seems to be monitored from the trachea at the entrance to the main bronchi.

086 – Carina Enlarged
Tracheal carina enlarged at the expense of both paths. The biopsy can reveal neoplastic embolisms of the submucosal lymphatics in 11% of the cases.
085 – Accented Folds
The longitudinal folds are preserved parallel but very accentuated and somewhat “separated” in this pulmonary atelectasis by extrinsic compression. Recall that in the trachea only the malignant conditions contiguous to its posterior wall “accentuate and separate” their folds, while the compressions of nonmalignant causes produce the bulge of the wall and the folds can be separated but not accentuated or “sink” in the mucosa, because it is not infiltrated but has only been pushed towards the tracheal lumen.
080 – Carina Lost
“Hidden carina.” Extensive compression in the tracheal route that produces the prolapse of the posterior wall. Towards the bifurcation deforms the light from the bronchi, losing the right bronchus. The carina it is hidden due to the compression.
073 – Endoscopic Semiology
“Bronchoscopy of the minimum changes”: In the distance, on the posterior wall, a small submucosal protrusion dominates among others that look out the tracheal light.
065 – Left Tracheal Bronchus
Left tracheal bronchus: infrequent variant of ventilation of the apicoposterior segment(LB1 + 2) of the left upper lobe, which now does it directly from
trachea.
062 – Klippel Feil Syndrome
Distribution anomaly: Tracheal bronchus.
Part of the right upper lobe is ventilated thanks to a bronchus that has shifted during the embryonic phase of lung development so that it is born directly from the trachea.
Sometimes, this bronchus only leads to the apical segment of the right upper lobe and is, in these cases, a “supernumerary” bronchus.
It can be associated to the fusion of cervical vertebrae (syndrome of Klippel Feil).
044 – Right Upper Lobe Bronchus
View from the right source bronchus: insinuates in hour 4 the entrance of the upper lobe and towards the bottom, the intermediate bronchus.
042 – Carina Normal
A) A and B different aspects of normal carina,
B)… in which its edge and angle can vary discreetly.
041 – Normal Trachea
Normal trachea and its bifurcation at the height of 4th or 5th dorsal vertebra.
