Fine-needle aspiration of the Warthin-like variant of papillary thyroid carcinoma: A report of three cases.

In English literature, there are only few reports of Warthin-like papillary thyroid carcinoma. We presented three cases and provided clinical, grossing, cytological, and histological correlation. In our point of view, the diagnosis of Warthin-like papillary thyroid carcinoma is feasible based on cytomorphological aspects. Usually those cases present moderately or highly cellular smears with many atypical Hürthle cells showing obvious papillary thyroid carcinoma nuclear features and without papillary structures, even if the inflammatory background is mild.
