转移到甲状腺肿瘤-肿瘤间转移-是非常罕见的。我们描述了第28例甲状腺肿瘤转移的病例，并回顾了甲状腺肿瘤作为受体的肿瘤转移的文献。所有病例均显示受体甲状腺肿瘤突然转变为形态学上不同的肿瘤。转移到原发性甲状腺肿瘤是同步的33%的情况下，异时性67%。滤泡性腺瘤是最常见的受体甲状腺肿瘤（16/28），乳头状甲状腺癌是最常见的恶性受体肿瘤（9/28）。在9例受体乳头状癌中，6例为滤泡型。肾细胞癌是最常见的肿瘤转移到原发性甲状腺肿瘤（9/28），其次是肺癌（6/28），乳腺癌（5/28）和结肠癌（3/28）。当甲状腺肿瘤出现二型性时，应考虑肿瘤间转移。
Metastasis into a thyroid neoplasm—tumor-to-tumor metastasis—is exceedingly rare. We describe the 28th documented case of a tumor metastatic to a thyroid neoplasm and review the literature on tumor-to-tumor metastasis involving a thyroid neoplasm as recipient. All cases showed a recipient thyroid neoplasm with an abrupt transition to a morphologically distinct neoplasm. Metastasis into primary thyroid neoplasm was synchronous in 33% of cases and metachronous in 67%. Follicular adenoma was the most common recipient thyroid neoplasm overall (16/28), and papillary thyroid carcinoma was the most common malignant recipient neoplasm (9/28). Of the 9 recipient papillary carcinomas, 6 were follicular variants. Renal cell carcinoma was the most common neoplasm to metastasize to a primary thyroid neoplasm (9/28), followed by lung (6/28), breast (5/28), and colon (3/28) carcinoma. Tumor-to-tumor metastasis should be considered whenever a dimorphic pattern is encountered in a thyroid tumor.
