Figure 2: Case #1: (a) Fine-needle aspiration cytology shows pseudoinclusions, elongation, enlargement, overlapping, and nuclear groves (Diff-Quik stain, ×400). (b) Presence of a multinucleated giant cell (arrow) (Diff-Quik stain, ×200). (c) The histopathology on low magnification of the case after resection shows a tumor with a follicular growth pattern surrounded by an intact capsule (H and E stain, ×100). (d) Higher magnification of the histopathology showing nuclear features of papillary thyroid carcinoma including pseudoinclusions, nuclear enlargement and clearing, and nuclear groves. This case was diagnosed as NIFTP (H and E stain, ×400)
