Stening 
Bulging of the wall at the entrance to the right source bronchus that ends in a formation reminiscent of the pustules. The biopsy of this mamelon is followed by the appearance of caseum, which is the beginning of the development of a tuberculous gangliobronchial fistula.
View of the very swollen laryngeal crown. It has lost the usual relief of its cartilaginous skeleton and a disseminated granulation is irregularly distributed in the mucosa. The vocal cords also affected, are asymmetrically thickened and deformed.
View of the precarinal trachea with bulging of the posterior wall. Its folds are well marked and “tensed” to surround the carina, grossly enlarged on its edge and its slopes. The congestion of the mucosa is irregular because its nutrient vessels were trapped by regional tumor growth. Alejandro Posadas Hospital
Carina in “saddle” or “book spine”. The tracheal wall and the main bronchi are displaced forward. There is moderate congestion of the mucosa. The border of the carina has disappeared due to the involvement of the subcarinal lymph nodes of group 7, due to a carcinoma.
Different forms of widening of the main carina, without disruption of the mucosa: a) Widening at the expense of the carinal edge. b) Widening at the expense of the anterior triangle. c) At the expense of the right slope. d) At the expense of both sides. e) Total widening of … Read more
Trachea severely affected by a carcinoma that sits on the posterior wall of the intrathoracic and precarinal portion with 50% light reduction.
This voluminous formation seems to occupy all the light and deprives us of explaining how distal pulmonary ventilation is achieved. The reason is that before the muscle relaxation caused by general anesthesia, the tracheal diameter was greater and thus allowed air passage through the periphery of this large occupant lesion.
Tumor of smooth surface and circumscribed aspect occupies the center of the tracheal lumen, reaching the height of its first ring.
Irregular edema in “street cobblestones” of the tracheal wall due to neoplastic embolisms in the submucosal lymphatics.
In this case, a cystic lymphangioma in the neck barely deflects the trachea. At hour 4 and 5, the imprint of the rings has been lost by the smooth and regular edema of the mucosa.
