Figure 4

A 32-year-old woman with minimally invasive adenocarcinoma in the right lower lobe. (A) Transverse thin-section CT (1 mm thickness) scan shows a 10-mm nodule (arrow) with air bronchograms. Its mean CT value is −755 HU. (B) Low-magnification (hematoxylin and eosin; original magnification, ×100) photomicrograph shows atypical pneumocytes proliferating along the thickened alveolar walls, a vascular invasion can be seen.
