Clinical image illustration of lung cancers that have features of T2. Squamous cell carcinoma of the right lower lobe of the lung (a) in a 57-year-old heavy smoker male. Chest CT with contrast showed the poorly enhanced, central tumor (a, arrow) measuring 4.4 cm with distal partial atelectasis/pneumonitis (arrowheads) of the right lower lobe of the lung. The stage is T2b in the 8th edition of lung cancer staging. A case of endobronchial lung cancer of the left upper lobe of the lung (b, c), involving the left main bronchus and left upper lobar bronchus with a maximum diameter of 2.7 cm (arrows). The involvement of main bronchus without touching the carina gives the cancer stage iT2a in the 8th edition of lung cancer staging.
