Papillary thyroid carcinoma, which is less malignant, is most often seen in children or young (before 40 years of age) female patients. The tumor grows slowly, but local lymph node metastasis has occurred. Ultrasound and CT examination are helpful for diagnosis, but nuclear scan is not significant. Treatment should be surgical, with lobectomy plus isthmus or total thyroidectomy. At the same time, attention should be paid to the protection of the recurrent laryngeal nerve and parathyroid glands, and intraoperative exposure of the recurrent laryngeal nerve is the key to avoid its damage. The paratracheal lymph nodes should be cleared at the same time, and total thyroidectomy should be performed if there is metastasis, and postoperative iodine 131 treatment. Radiotherapy and chemotherapy are not sensitive to this tumor.
