Abstract    Objective    To investigate the clinical characteristics of thyroiditis coexisted with thyroid carcinoma for the early diagnosis and treatment. Methods    The clinical data of patients with thyroiditis coexisted with thyroid carcinoma performed surgery between June 2008 and December 2009 at China-Japan Union Hospital of Jilin University were analyzed. Results    There were 210 patients with thyroiditis coexisted with papillary thyroid carcinoma (PTC) whom accounted for 26.0% (210/807) of thyroid carcinoma performed surgery and 41.0%(210/512) of thyroiditis during the same period. The rate of focal hypoechoic echo with irregular shape and illdefined edge of the border，diffuse hypoechoic echo，focal high-level echo and calcification which showed in preoperative sonogram was 89.1%（187/210），7.6%(16/210)，3.3%(7/210)，46.7%（98/210）respectively. Among them, 164 patients were performed lymph node dissection，and 83 (50.6%) patients of them had lymph node metastasis. Conclusion    The rate of thyroiditis coexistent with thyroid carcinoma is higher. The patients with irregular shape，illdefined edge of the border and focal hypoechoic echo in preoperative sonogram should be taken carefully and reviewed systematically，should be performed fine needle aspiration biopsy or operation actively.
