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 … Read more
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.
Complete loss of the normal anatomy of the main carina. View from the distal trachea in which the carina can not be seen, due to the existence of a necrotic surface tissue, with dehydrated purulent secretions that subocludes the entry of both bronchi source: adenocarcinoma.
Two circular whitish and bright areas in the center of the image. The effect is produced by the radiofrequency discharge through the thermocoagulation probe on the left.
Another vegetative formation that occludes the bronchial lumen but seems “sunken” in the mucosa because it drags the folds towards it.
Tracheal tumor with double origin: two large formations occupy the center of the tracheal lumen, although there is still a sufficient area for ventilation. In the image, the formations appear superimposed, but they have an independent origin constituted by pedicles that emerge from the tracheal wall. Both correspond to a single primary carcinoma.
Small “bronchial bulge” very erect. Remember better a rock. It is located at the end of the left source bronchus, near the crossroads and results from the invasion of the bronchial wall by a carcinoma. The mucosa is pulled, forming grooves. Further, the widened spur suggests underlying adenomegalies.
Bronchial light “stabbing”: an “intramural, intraluminal and infiltrating” carcinoma deforms the light from the left source bronchus. The intense edema and thickening of the bronchial mucosa contribute to the distortion and the marked reduction of the caliber. On the left wall it acquires a cordoned appearance that forms mamelons as it ascends and occupies the … Read more
In the form of a double tumor, this vegetative formation of large volume and with one of its ends partially necrotic, arises from the right source bronchus, but is also implanted in the tracheobronchial junction. The biopsy does not present any inconvenience but, naturally, it is necessary to avoid capturing the whitish covering of the … Read more
Although similar to the previous case, here are indirect signs of neoplastic process, contiguous to the lesion. Irregular edema with some small mamelons on a thickened carinal edge and distortion of the bronchial entrance right source, towards where the longitudinal folds of the posterior wall bend excessively.
