Experience of the Implementation of Rapid On-Site Evaluation in Ultrasound-Guided Fine-Needle Aspiration Biopsy of Thyroid Nodules.

Objective: To evaluate the effect of the implementation of the rapid on-site evaluation (ROSE) technique in ultrasound-guided fine-needle aspiration biopsy of thyroid nodules.

Materials And Methods: We conducted an observational and retrospective study approved by the Institutional Ethics Committee as an investigation without risk. Between January 2012 and December 2015, 892 ultrasound-guided fine-needle aspiration biopsy procedures were performed under ultrasound guidance.

Modern experience with aggressive parathyroid tumors in a high-volume New England referral center.

Background: Parathyroid carcinoma (PTCA) is an exceptionally rare malignancy, often with a clinical presentation similar to that of benign atypical parathyroid adenoma. Its low incidence portends unclear guidelines for management. Accordingly, thorough examination of clinical and pathologic variables was undertaken to distinguish between PTCA and atypical adenomas.
