Microscopic images, a The histological image of low-magnification. The left-upper side of image is FTC lesion and right-lower side of image is PTC lesion (× 20, hematoxylin–eosin). b High-magnification image of papillary carcinoma lesion. Typical nuclear findings of PTC, such as ground-glass nuclei, nuclear grooves (arrow heads), and pseudo-inclisions (arrows) are observed (× 400, hematoxylin–eosin). c High-magnification image of FTC lesion. Typical nuclear findings of PTC are not observed (× 400, hematoxylin–eosin)
