## Background: Papillary thyroid carcinoma is the most common malignant neoplasm of the thyroid gland, and fine-needle aspiration biopsy (fnab) often is the initial diagnostic method used in its detection. prior studies have shown that immunohistochemical staining for various cytokeratins in genera

โฆ Synopsis
The ultrasonographic findings and the use of ultrasonography combined with fine needle aspiration in 4 cases of metastases to the thyroid are reported. The primary neoplasms were bronchogenic carcinoma (2 cases), malignant melanoma (1 case), and renal cell carcinoma (1 case). Ultrasonography demonstrated bilateral (2 cases) and unilateral (2 cases) enlargement of the gland. In 3 cases, the texture of the gland was heterogenous and had hypoechoic areas. In 1 case a homogeneous mass containing calcified focus was seen. Ultrasonography was able to evaluate the extent of the disease in all patients by revealing metastatic nodes or jugular vein thrombosis. Finally, ultrasonography was useful in guiding fine needle aspiration. The potential use of ultrasonography in detection and biopsy of small thyroid lesions in patients with malignant disease is discussed.

## BACKGROUND. We reviewed the Massachusetts General Hospital experience with ultrasound-guided fine-needle aspiration biopsies (FNABs) of the thyroid to determine the indications, rate of unsatisfactory smears, correlation with excisional biopsy results, and verification of efficient use of perso

## Background: The purpose of this study was to evaluate the results of thyroid fine-needle aspiration (fna) and to determine the reasons for the discrepancies between the cytologic and histologic diagnoses. ## Methods: The authors evaluated the cytologic and histologic results of 133 fnas obtain
