“Bronchoscopy of minimum changes”: In the center of the image, the submucosal vessels are observed abnormally engorged. Some vascular “stops” can be appreciated usually present in the early infiltration of the bronchial wall.
“Bronchoscopy of the minimum changes”: In the distance, on the posterior wall, a small submucosal protrusion dominates among others that look out the tracheal light.
“Bronchoscopy of the minimum changes”: “Submillary” protrusions with creases accentuated of the mucosa and division spur widened at the entrance of the segmental basals.
“Bronchoscopy of the minimum changes”: roughness of the mucosa with turgid vessels in the proximity of a spur of the segmental basals.
“Bronchoscopy of the minimum changes”: Entry of the right lower lobe. A circular area of pale mucosa is observed under the spur of the middle lobe, in hour 11. A biopsy will be necessary to investigate carcinoma in situ.
At hour 11, a slight bulge of the apical segmental wall of the upper lobe (RB1) is the only endoluminal manifestation of a contiguous pulmonary nodule.
