Cytomorphology Features:

• The smears from both the left and right thyroid nodules are morphologically similar and show a moderate cellular smear arrange mostly in sheets with a background of abundant watery colloid. (fig. 1).
• Some papillary-like structures are present(fig. 2,fig. 3).
• The cells are follicular in nature with abundant cytoplasm and mildly enlarged but monomorphic round nuclei (fig. 2,fig. 3,fig. 4,fig. 5,fig. 6.
• The nuclei have somewhat open chromatin but lack prominent nucleoli (fig. 6).
• Nuclear grooves are not prominent and there are no pseudonuclear inclusions (fig. 6).
• There are also abundant flame cells present on the modified Wright-Giemsa stained slides (fig. 4,fig. 5).
• The flame cells are seen as follicular cells with translucent pink homogenous material that stains darker at the periphery which is seen within large cytoplasmic vacuoles.(fig. 5).
