Abstract

Fine-needle aspirations (FNAs) of parathyroid adenomas (PA) are infrequently encountered, brit the scant literature oil this topic emphasizes the difficulties in distinguishing them from thyroid neoplasms. We report on a case of an unsuspected intrathyroidal PA whose two FNA specimens mimicked almost perfectly the features of lymphocytic thyroiditis (LT). The smears from two FNAs of a "thyroid nodule" ill a 22-yr-old woman were received with a clinical diagnosis of "LT. " The cytological features of both specimens were similar and consisted of groups of epithelial cells in a background of numerous "naked" nuclei, interpreted as Hurthle cells and lymphocytes respectively and leading to a cytological diagnosis of LT. Subsequent surgical excision of the "nodule" revealed a large intrathyroidal PA. The oxyphil cells and chief cells (the latter devoid of cytoplasm) present in the PA resembledHurthle cells and lymphocytes respectively: in the FNA specimens. In conclusion, PA carl give a cytological picture almost identical to that of LT inFNA material. Important clues to the diagnosis of PA in FNA specimens include the presence sf prominent capillaries and the knowledge of a clinical history of hyperparathyroidism. (C) 1999 Wiley-Liss,Inc.
