This bright, congested and pale tumor, obliterates the entrance of the bronchus culminate in the left upper lobe, allowing only the passage of air to the lingula.
Combination. In the upper part of the image we can see the lesion that is still submucosally located, in the form of a protrusion that seeks to burst into the light, with its plethoric parallel vessels. In the center of the photograph the lesion is vegetative and thrives inside the bronchial lumen. Carcinoma.
Image corresponding to the previous case, after a recanalization of the right source bronchus.
There are diffuse inflammatory changes and blood in the path of the bronchus, which can be followed up to the lower lobe.
The folds in the source bronchus, deep and tortuous, are diverted to enter the upper lobe, but it is occluded.
Neoplastic tissue persists in the medial wall of the main bronchus and the tracheal carina is unrecognizable.
A voluminous vegetative formation settles in the tracheal carina and completely occludes the light of the right source bronchus and reduces that of the left.
The surface is irregular, with protrusions and increased vascularization in some areas. The tissue that obstructs the right main bronchus has been necrotic.
The posterior tracheal wall seems to be thrown forward and the edema has erased the folds.
Giant cell carcinoma.
A vegetative formation sits on the right side of the carina.
It presents multiple mamelons that give it an irregular and hyperemic aspect that contrasts with the general pallor of the healthy mucosa.
An ecchymotic dot is distributed in the area of the edge of the main carina and in its posterior triangle.
Squamous cell carcinoma.
Trachea: a giant cell carcinoma has completely infiltrated the wall.
Two ends of the cartilaginous rings are visible in the light as a result of the destruction of their mucosa, now covered by thick purulent secretions and suffering continuous dehydration due to being exposed to the turbulent airflow caused by local narrowness and inflammation.
