adenoma

The entrance to the upper right lobe bronchus is occluded. In this case, the adenoma presents a familiar aspect. The surface is smooth and a dense submucosal vascular network gives it an intense coloration.

Unlike the previous case, this adenoma that obstructs the left source bronchus presents several protrusions in its surface. Thus, it is easily confused with other types of tumors, especially due to the enlarged appearance of the tracheal carina.

The carial edge can be seen at 9 o’clock. At close range, a large mass occupies the right source bronchus, surmounted by bubbles formed by the instilled saline solution. The formation is smooth, as happens in most adenomas, and the entire mucosa of the surrounding tissue is completely normal.
