RESUMEN
This study evaluated the effectiveness of fine needle aspiration of thyroid nodules to reliably diagnose thyroid malignancy, using histopathology as the 'gold standard'. Out of 126 patients, 106 underwent surgery. The sensitivity, specificity and positive predictive value of fine needle aspiraton cytology to diagnose a papillary carcinoma in this study were 80.7%, 96.5% and 87.0% respectively. The accuracy of fine needle aspiraton cytylogy was 80.9%. Six cases that were benign by fine needle aspiraton cytology were confirmed to have malignant lesion by histopathological examination. High resolution ultrasonography could be useful in these situations for considering surgery.

During a period of 12 years, 874 salivary gland lesions were aspirated of which 740 (86.85%) were from parotid gland. Cystic, inflammatory & neoplastic lesions were 25.25%. 54.45% & 20.30%, respectively. Plcomorphic adenoma was the commonest benign & adenoid cystic carcinoma was the most frequent malignant tumors.On cytohistologic correlation, sensilitvity of cytology for diagnosing cystic, inflammatory, neoplastic lesions proved to be 93.3%. 95.7% & 100% respectively. Overall accuracy for cytodiagnosis of malignant salivary gland lesions in our study was 96.07%.
