ABSTRACT
Objective: To appraise the diagnostic role of fine needle aspiration cytology (F.N.A.C) as preoperative tool in patients with enlarged thyroid glands to avoid unnecessary surgery.
Study Design: Descriptive study
Place and Duration of Study: Department of Histopathology, Gulab Devi Hospital Lahore during period of three years i.e. January 2012 to December 2015.
Materials and Methods: A total of 185 patients were recruited for study of fine needle aspiration. Smears were made with the aspirated material and were stained with Hematoxylin-Eosin stain.
Results: There were 138 (74.59%) females and 47 (25.41%) male patients. Smears from 32 (23.19%) female patients were classified as malignant-Bethesda VI, 84 (60.87%) as benign-Bethesda II, 4 (2.9%) as suspicious for follicular neoplasia-Bethesda IV, 2 (1.45 %) as suspicious for malignancy-Bethesda VI, 3 (2.17%) as atypical-Bethesda-III and 13 (9.42%) aspirates were considered as unsatisfactory-Bethesda I. In case of 47 male patients, smears from 3 (6.38%) were classified as malignant-Bethesda VI, 38 (80.85%) as benign and 6 (12.77%) were considered as unsatisfactory-Bethesda I.
Conclusion: F.N.A.C is a safe, rapid, reliable and a simple test for discriminating between malignant and malignant lesions in nodules of the thyroid. It is currently practiced worldwide and proves to be the most cost-effective and dependable diagnostic procedure.
