Renal cell carcinoma is an unpredictable tumor that can recur many years after the original diagnosis. Metastasis of this tumor to the thyroid is an uncommon occurrence that can cause clinical and pathologic problems in diagnosis. The authors report case that present clinically as a palpable thyroid nodule 17 years after the primary renal cell carcinoma had been resected. This lesion appeared a solitary "cold" nodule on iodine 131 scan and was misdiagnosed as primary thyroid neoplasm. The diagnosis was facilitated by the use of immunohistochemical study.
肾细胞癌是一种不可预测的肿瘤，可在初次诊断多年后复发。这种肿瘤转移至甲状腺的情况并不常见，可能会在诊断中引发临床和病理问题。作者报告了这样一例病例，在原发性肾细胞癌切除17年后，临床上表现为可触及的甲状腺结节。该病变在碘131扫描中表现为孤立的“冷”结节，被误诊为原发性甲状腺肿瘤。免疫组化研究有助于明确诊断。
