ROLE OF FINE NEEDLE ASPIRATION CYTOLOGY IN DIAGNOSIS OF NEOPLASTIC AND NON NEOPLASTC LESIONS OF THYROID GLAND

Dr Bidyut Dutta, Dr Ripunjay Deka

Abstract :

Introduction: Thyroid nodules are common clinical findings and have a reported prevalence of 4–7% of the adult population, however <5% of adult thyroid nodules are malignant. The thyroid nodules are more common in women and the incidence increases with age, a history of radiation exposure and a diet containing goitrogenic material. . In recent years, fine needle aspiration cytology (FNAC) has supplanted most other tests for preoperative evaluation of thyroid nodules and increasingly used as a diagnostic procedure due to its simplicity, low cost and absence of major complications. Aim and objective : Aim of the study was cytological evaluation of neoplastic and non neoplastic lesions of thyroid gland . Materials and method : The present study on thyroid nodule was carried out at Fakhruddin Ali Ahmed Medical College and Hospital, Barpeta from 1st june 2015 to 31st May 2016. This was a prospective study in which a total of 50 patients underwent FNAC of thyroid gland. Histopathological examinations was done where biopsies were available Results : 50 patients underwent FNAC of thyroid gland . The results of the FNA diagnosis showed that 4 (8%) of the patients had FNAs , which were inadequate for cytological assessment , 35 (76.08 %) patients had benign lesions , 8 (17.39%) had lesions that were suspicious for malignancy , and 3 (6.52%) had malignant neoplasm . The correlation of the FNAC findings with the histopathological diagnosis , showed that our FNAC diagnostic accuracy rate was 96.77 % , with a sensitivity of 66.67% , and specificity of 100 % . Conclusion : Cytological diagnosis of both neoplastic and neoplastic lesions of thyroid gland can be established with the help of FNAC which is of highly accurate diagnostic value .
