Fig. 6. A 56-year-old man with lepidic predominant invasive adenocarcinoma (LPA). A. Initial transverse 2.5 mm thin-section CT scan shows 14 mm pure ground-glass nodule (GGN) with complex shape and marginal irregularity in the left lower lobe with no interval change after a 12-month follow-up CT. B. Photomicrograph (hematoxylin and eosin stain; magnification, × 1) demonstrates LPA non-mucinous type with complex shaped nodule (arrows) and 7 mm stromal invasion (arrows). Fig. 6.
