Papillary carcinoma of thyroid is the most common type of thyroid neoplasm which is usually confined to the thyroid and tends to metastasize to regional lymph nodes. Distant metastasis occur in up to 15% of cases. Thymic metastasis from any malignant carcinoma is extremely rare with only four cases reported in medical literature. We report a case of papillary carcinoma of thyroid metastasizing to ectopic cervical thymus which has not been previously reported.

甲状腺乳头状癌是最常见的甲状腺肿瘤类型，通常局限于甲状腺，且易于向局部淋巴结转移。远处转移发生在多达 15%的病例中。任何恶性肿瘤的胸腺转移极为罕见，文献中仅报告了 4 例。我们报告了一例甲状腺乳头状癌转移至异位颈胸腺的病例，此前尚未有报道。
