Metastatic thyroid carcinoma is clinically silent and found only at autopsy in most instances. Renal cell carcinoma (RCC) is the most common and constitutes 56% of all secondary malignancies. However, preoperative distinction between primary and secondary thyroid neoplasms is often challenging. Fine needle aspiration is helpful in establishing a correct preoperative diagnosis. A local surgical resection is curative if prompt preoperative diagnosis is established. We hereby report a case of isolated metastatic RCC to the thyroid in a 65-year-old woman, diagnosed by fine needle aspiration cytology and later confirmed with histopathological examination.
转移性甲状腺癌在临床上通常没有症状，多数情况下仅在尸检时发现。肾细胞癌（RCC）是最常见的继发性恶性肿瘤，占所有继发性恶性肿瘤的56%。然而，术前区分原发性和继发性甲状腺肿瘤往往具有挑战性。细针穿刺有助于术前做出正确诊断。如果能及时做出术前诊断，局部手术切除可治愈。我们在此报告一例65岁女性孤立性甲状腺转移性肾细胞癌病例，通过细针穿刺细胞学诊断，随后经组织病理学检查确诊。
