Representative microphotographs from EBUS-guided thyroid aspirations. Representative microphotographs from EBUS procedure: (A) papanicoulau stained smear and (B) cell block showing a poorly differentiated adenocarcinoma with papillary features. Immunohistochemistry showed these tumor cells with strong and diffuse positivity for TTF1 (C), focal staining for carcinoembryonic antigen (D), strong diffuse positivivty for CK7 (E), and strong diffuse positivity for pancytokeratin. (G) and (H) show papanicoulau stained smear with clusters of benign follicular cells and colloid. (I) Cell block preparation showing thyroid follicles with colloid consistent with follicular nodule.
