Fine-Needle Aspiration Cytology of Parathyroid LesionsLegesse, Teklu MD; Staats, Paul N. MDPathology Case Reviews: September/October 2015 - Volume 20 - Issue 5 - p 227–229 doi: 10.1097/PCR.0000000000000111 Case Reviews Buy Abstract Author InformationAuthors Article MetricsMetrics Parathyroid tissue is not uncommonly encountered in evaluation of “thyroid nodules,” either due to radiologic misinterpretation of a parathyroid neoplasm as thyroidal in origin or due to incidental sampling during aspiration of a thyroid nodule. Recognition of the cytologic features of parathyroid is important to prevent misdiagnosis of these relatively common lesions and subsequent inappropriate surgical management. In addition, fine-needle aspiration is occasionally used in the preoperative workup of patients with hyperparathyroidism. Fine-needle aspiration can be used as an adjunct to imaging for preoperative localization of hyperfunctioning parathyroid tissue, which helps to minimize the extent of surgical exploration. This report reviews the cytomorphologic features of parathyroid lesions, differential diagnostic considerations, and ancillary methods that can be used to arrive at the right diagnosis.
