Evaluation of Fine Needle Aspiration Cytology Role in Diagnosis of Thyroid Lesions
Background: Fine needle Aspiration cytology (FNAC) has been a method of choice for the diagnosis of various pathological disorders. Diagnosis of thyroid lesions has long been considered a diagnostic grey area in thyroid cytology which often leads to false negative and false positive cases. Therefore the present study was designed to assess the efficacy of FNAC in the diagnosis of thyroid lesions. Subjects and Methods: This was a retrospective study of FNAC of thyroid lesions performed on patients in the pathology department of Teerthanker Mahaveer Medical College and Hospital. A total of 50 patients underwent FNAC followed by thyroid surgery subsequently. Results of FNAC were compared to the final histopathological diagnosis. Results: Results of the present study showed that out of 50 thyroid lesions patients, 37 were females (74%) while 13 were males (16%). Most of the cases of thyroid lesions were benign (76%) in nature followed by Follicular neoplasm/suspicious for a follicular neoplasm (FN/SFN). Atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) was recorded in 2 cases. Malignancy was observed in 4% cases whereas, 2% of cases showed suspicious malignancy. Conclusion: Findings of the present study suggest that FNAC is very use full in diagnosis of thyroid lesions as it is accurate, easy to perform, less time taking and cost effective compare to other contemporary diagnostic tools for thyroid lesions. Moreover, if results of the FNAC reported according to Bethesda system; it helps in categorizing the thyroid lesions and severity of the risk to the patients. This can further help in prompt and effective management of the thyroid lesions.
