Distinguishing parathyroid and thyroid lesions on ultrasound‐guided fine‐needle aspiration: A correlation of clinical data, ancillary studies, and molecular analysis

Abstract

Lesions with follicular lesion of undetermined significance-like or oncocytic features are prone to misdiagnosis. The current study identified distinct cytologic patterns in parathyroid lesions suggestive of parathyroid origin, which, together with PTH immunostains or assay, molecular studies, or sestamibi scans, aid in distinguishing parathyroid from thyroid lesions.
