In this paper, we review those pathologic entities that may mimic papillary thyroid carcinoma. These include specimen preparation and handling issues such as decalcification, frozen section, and artifacts occurring following fine-needle aspiration (FNA). Also discussed are true disease entities, including chronic lymphocytic thyroidits, benign papillary hyperplastic lesions, hyalinizing trabecular neoplasm, and post-FNA changes. Both the cytologic and histopathologic preparations containing these changes are reviewed and illustrated; guidelines for distinctions among these entities are provided.
