Pak J Med Health Sci Jan ;13(2):408-10.

Aim: To study the association of thyroid scan, thyroid function tests and size of thyroid nodule with the cytological diagnosis of the thyroid swellings. Design : Descriptive cross-sectional study Place and duration of study: Pathology department, King Edward Medical University (KEMU), Lahore from November 2018- April 2019. Methods: The patients presenting to the pathology department of KEMU for fine needle aspiration cytology (FNAC) of their thyroid nodule were selected and its results were correlated with the size of thyroid nodule, thyroid function tests (TFTS) and thyroid scan. Data was analyzed by SPSS 23. Chi Square test and cross tabulations were used to measure association between thyroid scan, FNAC and size. Results: A total of 50 patients with thyroid nodules presenting at Pathology department were selected. The mean size of thyroid nodule was 3.64 +/-1.651 cm. It ranged from 2-10 cm. 29(58%) people had size between 3-5cm. 21 (42%) had size greater than 5 cm. On thyroid scan, many nodules 35(70%) were cold, 2(4%) nodules were warm, 1(2%) hot nodule and 12(24%) nodules were found to have MNG. Out of total 50 FNAC, 48(96%) were benign and 2(4%) were malignant. Conclusion: We conclude that among all nodules , cold nodules are mostly malignant and FNAC should only be done for cold nodules. Size of thyroid nodule has no association with malignancy of nodule.
