A voluminous vegetative formation settles in the tracheal carina and completely occludes the light of the right source bronchus and reduces that of the left.
The surface is irregular, with protrusions and increased vascularization in some areas. The tissue that obstructs the right main bronchus has been necrotic.
The posterior tracheal wall seems to be thrown forward and the edema has erased the folds.
Giant cell carcinoma.
