甲状腺舌管内甲状腺癌较为少见,Saharia 收集文献报道仅76例,本院在11年内即遇到3例,皆是甲状腺乳头状腺癌。手术时发现肿瘤都有蒂柄通向舌骨,提示肿瘤系起源于甲状舌管内的异位甲状腺而非起源于甲状腺的锥体叶。 Thyroid tongue thyroid cancer is rare, and Saharia collected only 76 cases in the literature. This hospital encountered 3 cases within 11 years and all of them were papillary thyroid carcinoma. During operation, the tumors were found to have pedicles leading to the hyoid bone, suggesting that the tumor originated from the ectopic thyroid gland within the thyroglossal duct rather than from the thyroid.
