case_images: Hematoxylin and eosin-stained sections showed that the described lesions correspond to PTC characterized mainly by papillary structures "(shown in Figure 1(a))". The lining epithelium consisted of medium-sized cells with eosinophilic cytoplasm and distinctive nuclear features, namely, nuclear overlapping, chromatin clearing, irregular nuclear contour, and nuclear grooves and pseudoinclusions "(shown in Figure 1(b))".
case_images: (a) (x400) Immunohistochemical stain for IL-6 proved to be positive in cancer cells. (b) (x400) A small proportion of cancer cells displayed immunoreactivity for CEA.
