The cytopathology results of 698 fine needle aspirations (FNA) of thyroid nodules from the patients who visited Srinagarind Hospital from January 1984 to July 1990 were analyzed.  Five hundred FNA (71.6%) were cytologically benign, 40 FNA (5.7%) were suspicious for malignacy, 21 FNA (30%) were malignant, and 137 FNA (19.6%) were unsatisfactory.  The histologic diagnosis in 101 cases were compared with cytologic diagnosis to determine the accuracy of Fna cytology of thyroid lesions.  From 24 diagnosis of malignancy reported by histology, 14 malignancies, 1 suspicious lesion, 2 benign lesions and 7 cystic lesions were found by FNA. No false positive were recorded.  Sensitivity, specificity and accuracy of FNA diagnoses were 87.5%, 100% and 96.15%, respectively.
