Background: Several studies all over the world have proposed the association of Papillary Thyroid Carcinoma with Hashimoto Thyroiditis, Lymphocytic Thyroiditis and Multinodular goitre. Papillary Thyroid Microcarcinoma (≤ 1cm size lesions) which are detected incidentally on histopathological examination of thyroidectomy specimens can progress to clinically evident Papillary Thyroid Carcinoma if left untreated. In this study, we aim to determine the types of lesions associated with Papillary Carcinoma Thyroid and to study the most commonly associated lesion, age group and gender affected. Materials and Methods: A total of 74 cases of Papillary Thyroid Carcinoma who underwent thyroidectomy at a tertiary care hospital in Kerala were included in the study. The association between types of lesions, age group and gender were studied and the data obtained was analyzed using Chi Square test. Results: Mean age of the study population was 47 years and majority were females (86.5%). Out of 74 cases of Papillary Thyroid Carcinoma, 58 cases (78%) had associated lesions. The most common associated lesion with Papillary Thyroid Carcinoma was Multinodular goitre (59%), followed by Lymphocytic Thyroiditis (50%) and Hashimoto Thyroiditis (16%).Among the 74 cases, 17 cases (23%) were of Papillary Thyroid Micro carcinoma. Conclusion: It was found that there was significant prevalence of associated lesions with Papillary Thyroid Carcinoma. Hence all non neoplastic lesions of thyroid which are usually managed conservatively require a strict follow up to rule out the possibility of developing Papillary Thyroid Carcinoma. This will go a long way in preventing the morbidity and mortality that could arise in Papillary Thyroid Carcinoma.
