Figure 2

A 48-year-old woman with atypical adenomatous hyperplasia in the right upper lobe. (A) A transverse thin-section CT (1 mm thickness) scan shows a pure GGN (arrow) with a maximum diameter of 6 mm, a well-defined, smooth interface and a mean CT value of −723 HU. (B) A low-magnification (hematoxylin and eosin, original magnification, ×100) photomicrograph shows atypical, type II pneumocytes and/or Clara cells proliferating inconsecutively along the alveolar walls, no vascular invasion is seen.
