One-stage resection of four genotypes of bilateral multiple primary lung adenocarcinoma: A case report

Figure 3 The left side of the image is a computed tomography image. The red arrow indicates the location of the nodule. The upper right side indicates a low-power microscopic pathological image, and the lower right side indicates a high-power microscopic pathological image. A: The left upper pulmonary nodule is an adenocarcinoma in situ, with adherent growth and obvious cell atypia; B: The left lower lung nodule is an acinar adenocarcinoma with glandular arrangement, invasive growth, significant atypia of cancer cells, and proliferation of interstitial fibrous tissue; C and D: The right upper and right lower nodules are microinvasive adenocarcinoma. The cancer cells adhere to the wall; the cell atypia is significant; and the focus shows invasive growth.
