(a and b) Multinucleated giant cells and tumor cells are seen in fine-needle aspirationof PTC. Multinucleated giant cells carry variable number of nuclei (ThinPrep, Papanicolaou stain, 400). WebThe salient cytologic features included cellular smears; multinucleated giant cells in 100% of cases, some ingesting colloid or neutrophils; fibrous fragments with enmeshed inflammatory cells were a constant feature; follicular cells were scant to absent in most cases. Granulomas were rare.

Web7 mai 2024 · Multinucleated foreign body-type giant cells with bizarre cell shape can be seen in PTC cases with papillary growth (Fig. 1.7). The cytoplasm is dense and not dirty. The nuclei may resemble those of PTC cells, but they are histiocytic in origin. ATC may be associated with osteoclast-like multinucleated giant cells (Fig. 1.8). The findings ... WebMultinucleated giant cells (MNGCs) are reported in many thyroid lesions. This study examines whether their quantity and quality can help in the differential diagnosis. … WebThe presence of large MGCs with dense cytoplasm in a thyroid nodule without clinical evidence of thyroiditis should prompt careful exclusion of associated PTC.
