FIGURE 1 ICG fluorescent imaging during pulmonary metastasectomy. A small lesion (arrow in A) taking up ICG is visualized with the Photodynamic Eye machine (B).
FIGURE 2 Microscopic findings of ICG-stained false-positive specimens. Thrombus (A) and well-circumscribed fibrotic mass accompanying osteoid and chondroid metaplasia (B), suggesting histological changes after the regression of a tumor, were seen in several specimens. Hemorrhage with hemosiderin-laden histiocytes was commonly seen (C). Hematoxylin–eosin.
FIGURE 3 Microscopic findings of metastatic lesions from hepatoblastoma. A. Representative example of ICG-positive, tumor-positive specimens. Image shows embryonal type. B. Representative example of ICG-negative, tumor-positive specimens, which displayed more atypical features than ICG-positive tumors. Hematoxylin–eosin.
