Another form of presentation of the endobronchial tumor that occurs frequently: only whitish formation. It is no more than necrotic tissue on the surface because it is the furthest point from its base of vascularized implantation. The secretions cover it and can dry out due to the disturbance in the airflow produced by the tumor.
Vegetative tumoral formation that occludes the right upper lobe, which also shows a noticeable widening of its spur. The lesion appears with freshly emitted blood due solely to the cough that occurred during the endoscopic exploration. Insufficient local anesthesia will trigger coughing during the examination and spontaneous bleeding will make it difficult to see and … Read more
Close-up image of a bulky tumor that completely obstructs the bronchial lumen. Note the particular arrangement of the surface vasculature. Some vessels interrupt their journey intermittently. It is another expression of the “vascular stop” because of the tumoral infiltration of its wall.
Macroscopic appearance very common in neoplastic processes. The sub-occlusion of the bronchus is formed by tissue that develops in the light (center of the image), and in its upper part the proliferation still respects the mucosa, at least on its surface. The vessels are engorged, with the typical changes in their color.
On this enlarged bronchial spur, the engorged vessels that form “islands” in their tortuous path are observed. Biopsy: adenocarcinoma. Alejandro Posadas Hospital
All signs present: Vegetative tissue, with whitish necrotic areas, mamelons, edema, changes in vascularization and coloration with more or less congestive areas, in this carcinoma that occludes the intermediate bronchus.
In this tracheal compression, the magnitude is such that there is no light in the right source bronchus and a large reduction in crescent in the left. The “Y” stent is indicated to recover light and threatened ventilation.
Severe left lateral compression that gives curvature to the trachea in addition to the reduction of the transverse diameter.
“Infundibuliform stenosis” All the planes of the bronchial walls meet at a point where the bronchial light no longer exists.
“Light in cleft” In this case bilateral compression is quite symmetrical and produces a linear narrowing of the bronchial lumen. In the image the affected segment is the upper part of the lingula (LB4).
