Thyroid lesionsmay be developmental, inflammatory, hyperplastic, and neoplastic.Aim: This study aims to study the spectrum of various lesions of the thyroid and various histopathological patterns of thyroidlesions.Materials and Methods: In this retrospective observational study, a total of 100 thyroid tissue specimens were examined.Relevant clinical information such as patient age, gender, and clinical presentation and other information such as fine-needleaspiration cytology, ultrasound, and surgical findings were obtained.Results: Non-neoplastic lesions accounted for 84 cases (84%) and neoplastic lesions constituted 16%. The most commonnon-neoplastic lesion was multinodular goiter (MNG) (43%), followed by colloid goiter (29%), Hashimoto thyroiditis (9%), andthyroglossal duct cyst (3%).Conclusion: In our study, thyroid diseases showed definite female predominance, with most of them occurring in an age groupof 31–40 years. MNG is the most common disease occurring clinically, radiologically, and cytologically. Follicular adenoma wasthe most common benign neoplastic disease.Thyroid lesionsNon-neoplasticNeoplastic lesionsJournal ArticleIndiaAssociate Professor, Department of Pathology, Coimbatore Medical College, Coimbatore, Tamil Nadu, IndiaAssistant Professor, Department of Pathology, Coimbatore Medical College, Coimbatore, Tamil Nadu, India
