Papillary Hürthle-cell tumors of the thyroid are composed of oxyphilic cells with a prominent papillary component. Their biologic behavior appears to be comparable with that of conventional papillary thyroid carcinomas. The literature on the fine-needle aspiration cytology of these tumors is scanty. The cytologic findings of three such cases are reported here. The findings suggest that most papillary Hürthle-cell tumors cannot be differentiated from other types of Hürthle-cell tumors cytologically.
