Abstract    Papillary thyroid microcarcinoma is the most common type of thyroid microcarcinoma. Other uncommon variants have been described including follicular variant papillary thyroid microcarcinoma，follicular thyroid microcarcinoma，Hurthle cell microcarcinomas，tall cell variants，diffuse sclerosing variant and so on. Total/near total thyroidectomy with neck dissection may be the optimal surgical procedures for high-risk thyroid microcarcinoma patients who have gross lymph node metastasis，extrathyroid involvement and distant metastasis at presentation.  Loboisthmusectomy may be a sufficient treatment of choice for patients with low-risk thyroid microcarcinoma when thyroid cancer less than 1 cm，unifocal，intrathyroidal，without extrathyroid invasion and lymph node metastasis.

Key words: thyroid microcarcinoma, papillary thyroid microcarcinoma, follicular variant, follicular, tall cell variants

摘要：

在甲状腺微小癌中乳头状癌最多见，其他少见的特殊病理类型有滤泡变异型、滤泡型、嗜酸细胞型、高细胞亚型、弥漫硬化压型等。对有明显的颈部淋巴结转移、甲状腺外浸润和远处转移的高危病人，理想的手术方式是甲状腺全或近全切除术+淋巴结清扫。甲状腺癌肿瘤直径<1 cm、单发病灶局限于腺叶内、无甲状腺外浸润、无颈部淋巴结转移、复发危险度低的病人，可以行甲状腺腺叶+峡部切除术。
