Abstract: Thyroglossal duct carcinoma is an extremely rare disease,with thyroglossal duct papillary carcinoma being the most common type.By reviewing the diagnosis and treatment processes of 2 cases of thyroglossal duct papillary carcinoma and combining with relevant domestic and foreign literature,the preoperative diagnosis and surgical methods of this disease are summarized.Ultimately,the research findings indicate that fine-needle aspiration can improve preoperative diagnostic efficacy,and surgery remains the preferred treatment for thyroglossal duct carcinoma at present.
