Objective: The aim of this study is to delineate clinical and histopathological features of thyroid Papillary Carcinoma detected in thyroidectomies submitted to analysis in Anatomic Pathology Department at University Hospital In Federal University of Sergipe. Methods: This is a retrospective and descriptive study of thyroidectomy specimens diagnosed over a period of nine years. Results: Detections rates of Papilary and Micropapillary Carcinomas were 30,7% and 20,5% respectively. Parameters frequency, in tumors less than 10,0 mm and greater were, repectively: positive surgical margins (4,6%; 33,3%), extrathyroid infiltration (8,33%; 66,6%), angiolymphatic invasion (0; 8,3%), psamomatous calcifications (20,8%; 83,3%), central lymph nodes metastasis (16,6%; 50%).
