293 – Bronchial Leiomyosarcoma

293 - Leiomyosarcoma

Leiomyosarcoma: This image is not very precise, but there is a red wine formation that occupies all the light of the middle lobe bronchus.

The bubble crown indicates that the lesion does not infiltrate the entire perimeter of the wall, or that there is a pedicle, and that ventilation is still possible.

Leiomyosarcoma in a bronchial neoplasm with low frequency of presentation.

287 – Esophageal carcinoma

287 - Esophagus Carcinoma

Confusing image in which the anatomical structures are difficult to recognize.

The tracheal domed ceiling ends in the anterior carinal triangle, barely visible.
On your right the source bronchus.

Large amount of blood and exudates fill the free space between the disordered tissues that occupy the light, occluding the left source bronchus.

A carcinoma of the esophagus has destroyed the posterior wall of the main bronchus, as it always does in this location given its vicinity, and a set of esophageal mucosa, and neoplastic tissue
now occupies the airway.
