[Table/Fig-2]:

a-c) FNA smears showing Giemsa stain: (a) Three dimensional groups and microfollicles of monotonous cells with nuclear crowding and overlapping (FTC x400). (b) Mono layered sheets, papillary fragments with fibrovascular core and regular borders (PTC, x200); inset - nuclear features of PTC (arrowhead - intranuclear inclusion) (x400) . (c) High cellularity with fish school pattern and spindle cells (MTC, x200); inset – plasmacytoid cells mixed with smaller oval cells (x400). (d) Large cells with pleomorphic nuclei (ATC, H&Ex400); inset - FNA smear showing pleomorphic tumour giant cell (Giemsa x400). (e) PTC – Papillae containing fibrovascular cores lined by low columnar epithelial cells (H&E x200); inset-optically clear nuclei (arrow - intranuclear inclusion) (x400). (f) MTC – Spindle cells arranged in fascicles with fine nuclear chromatin (x400).
