Abstract :

Background:– Fine needle aspiration cytology (FNAC) is the first line diagnostic procedure for thyroid swellings which helps to select patients who require surgery for a neoplastic disease from those patients who can be followed clinically or treated medically. The Bethesda system for reporting thyroid cytopathology (TBSRTC)[1] was introduced in 2007 in an attempt to standardize international terminology and to categorize morphological criteria in fine–needle aspirations (FNAs) of thyroid swellings. Objective:– The aim of the present study is to characterize the pattern of various thyroid lesions on FNAC along with age and gender distribution in patients presenting with thyroid disorders and to assert its utility in differentiating neoplastic from non–neoplastic lesions. Methodology:– A hospital based cross sectional study conducted over a period of fifteen months. FNAC of 120 cases of clinically diagnosed thyroid lesions were done, smears stained and observed under the microscope. Results:– In the study majority of cases were females (F–93 cases, 77.5%) compared to males (M–27 cases, 22.5%) with M:F ratio = 1:3.4. Age of patients ranged from 8 years to 75 years, with cases occurring commonly in the age group of 21–30 years .The most frequent thyroid lesions were benign (103 cases, 85.8%), followed by suspicious for follicular neoplasm (8 cases, 6.7%), malignant (7 cases, 5.8%). 2 cases (1.7%) were unsatisfactory for evaluation. Among benign lesions (103 cases, 85.8%), goiter (93 cases, 90.3%) was the most common followed by Hashimoto’s thyroiditis (06 cases, 5.8%), granulomatous thyroiditis (03 cases, 2.9%), primary hyperplasia (01 case, 1%). Among the malignant cases (07 cases, 5.8%) the most common was papillary carcinoma (04 cases, 57.1%) occurring commonly in females (03 cases, 75%).This was followed by anaplastic carcinoma (02 cases, 28.6%), medullary carcinoma (01 case, 14.3%). Conclusion:– We conclude that a diverse group of diseases affect the thyroid, ranging from inflammatory to neoplastic diseases with their characteristic age and sex pattern. FNAC aided by a careful clinical history and supporting investigations offer optimum results and helps avoiding unwanted surgical procedures.
