Diseases of the thyroid gland are common and comprise a spectrum of entities causing systemic disease or localised abnormalities in the thyroid gland such as nodular enlargement or a tumour mass. Thyroid cancer is a relatively rare malignancy, but it is the commonest endocrine cancer accounting for 92% of all endocrine malignancies. The aim of the study was to describe the pattern of thyroid malignancies in thyroidectomy specimens.



This study was done in the Department of Pathology, Saveetha Medical College and Hospitals, Chennai, over a period of one year from June 2017 to May 2018. It is a retrospective study. The thyroid diseases were classified on histological grounds into non-neoplastic and neoplastic lesions that were further subclassified as benign and malignant as per WHO histological classification of thyroid tumours.



Age of the patient ranged from 14-70 years with a male to female ratio of 1:6.14. Most patients presented with multinodular goitre and most were in euthyroid state. Sensitivity of FNAC was found to be 67% and specificity was found to be 100%. Accuracy was found to be 100%.Negative predictive value (NPV) was found to be 92.7%.



Papillary carcinoma was the commonest malignant lesion whereas follicular adenoma was the commonest benign neoplasm.
