Fine Needle Aspiration Cytology (FNAC) of Thyroid Neoplasms

Background: Evaluation of diagnostic value of fine needle aspiration cytology in diagnosis of neoplastic lesions of thyroid gland.

Materials and method: it is a crossectional study of 47 neoplastic lesions of thyroid out of 343 thyroid FNAC. Results were analysed according to the Bethesda classification . Histopathological diagnmosis were considered the gold standard.

Results: Total 47 neoplastic cases were analysed. Female to male ratio was 4.2:1, and common age group was 21-40 years.Twoentycases(42.55%) were diagnosed as follicular neoplasms ,22 cases(46.81%) as malignant and 5 cases(10.64%) as suspicious for malignancy.Papillary carcinoma was most commonly encountered malignant neoplasm (31.91%). Cytologicdiagnosis were compared with corresponding histologic ones whenever possible. FNAC achived a diagnostic accuracy of 95.0% and false positive rate of 5.0% .

Conclusion: FNAC is highly accurate first line diagnostic technique for the evaluation of neoplastic lesions of thyroid.
