A Study of Cyto-Histological Correlation in the Diagnosis of Thyroid Swelling

There is some "grey zone" in thyroid cytology where the diagnostic efficacy declines sharply rendering it difficult to categorize the lesions resulting in discrepancy. So, a cross-sectional study was conducted to determine the accuracy of FNAC in diagnosis of thyroid swelling and to assess the correlation between preoperative cytological diagnosis and post operative histopathological diagnosis. It was observed that FNAC is reliable, safe and accurate method as a first line of evaluation in thyroid swelling before the surgery. FNAC is more sensitive in detecting thyroid gland malignancy and therefore histopathological analysis still remains essential for final diagnosis.
