Adenocarcinoma in situ (AIS). One mixed ground-glass nodule was found in the upper lobe of the left lung; its shape is irregular, part of the boundary is blurry, and the adjacent pleura is deformed by traction (a, b). Pathology (c): the tumour cells adhered to the alveolar cell wall, and the basement membrane was intact as observed under a microscope. (HE staining, × 200)
