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.
