FIG. 2.

Representative samples of the following cytological categories. (A) Suspicious for follicular neoplasm: Clusters of follicular cells arranged in microfollicles. (B) Suspicious for Hürthle cell neoplasm: Cluster of Hürthle cells arranged in a flat sheet with larger nuclei with prominent nucleoli. (C) Suspicious for papillary carcinoma: Cluster of follicular cells with round nuclei and minimal size variation and nuclear grooving. Note the presence of two distinct intranuclear inclusions that raise the possibility of papillary carcinoma (marked with arrows).
