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
Mucous secretions located in the right source bronchus, which is occluded by a formation that gives it the appearance of “bottom of sac.” This term should be reserved for the description of the bronchial stumps by surgical amputation during pneumonectomies.
Although the flexible bronchoscope still runs through the intermediate bronchus, a whitish image due to the small tumor occluding a segment of the base can be guessed in the distance.
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.
Deformation of the entrance of the lower left lobar bronchus. Its circumferential contour is now wavy. There are changes in vascularization and several submucosal protrusions.
This pyramidal formation that emerges from the left source bronchus can be confused with a bronchial tumor, although it is an aged and retained blood clot that acquires this coloration composed of gray and burgundy. Note the normal environment of the surrounding mucosa.
