Correlation of Fine Needle Aspiration Cytology and Histopathology of Solitary Thyroid Nodule

Abstract

Fine needle aspiration cytology is commonly used to screen lesions in pathology including thyroid lesions.It is mainly used to identify malignant lesions which then can be excised and examined by histopathology. FNAC uses the cytological features to distinguish between benign and malignant lesions. In our study, 60 patients were taken, age ranging from 15 to 65 years. Initially patients were clinically evaluated and FNAC followed by histopathological examination was performed on the excised thyroid lesions.In our study, majority were females and neck swelling was the commonest presentation. Majority were benign lesions. Malignant lesions were 18%.While comparing lesions in FNAC and histopathology, sensitivity of FNAC was found to be 84.61% and specificity to be 93.61%. The accuracy of FNAC obtained was 91.6 %.Thus,sensitivity and specificity of FNAC was high and can be used to screen thyroid solitary nodules
