Thyroid cancer is the most common malignant tumor of the endocrine system. There have been some reports on kidney cancer with thyroid metastasis. However, kidney cancer has rarely been detected during thyroid cancer surgery.
We present a rare case of kidney cancer with thyroid metastasis, combined with thyroid carcinoma. A 66-year-old woman was admitted to our hospital in September 2021 due to enlarged left thyroid nodules for two years. The patient was diagnosed with a left thyroid nodule on physical examination in 2012. Extended radical resection of the thyroid cancer was performed. Intraoperatively, two thyroid lesions were identified. Thus, the patient was definitively diagnosed with kidney cancer with thyroid metastasis and papillary thyroid carcinoma. Furthermore, two metastatic nodules due to kidney cancer and one metastatic lymph node lesion due to thyroid cancer were found in the loose connective tissue adjacent to the thyroid.
Kidney cancer with thyroid metastasis and thyroid carcinoma rarely co-occur, and it is difficult to identify the primary tumor. Although clinical examination methods are increasingly updated, the past medical history and physical examination are still very important.
甲状腺癌是内分泌系统最常见的恶性肿瘤。有一些关于肾癌伴甲状腺转移的报道。然而，在甲状腺癌手术中很少发现肾癌。
我们报告了一例罕见的甲状腺转移合并甲状腺癌的肾癌病例。一名 66 岁女性因左甲状腺结节增大两年于 2021 年 9 月入住我院。患者于 2012 年体检时发现左甲状腺结节，行甲状腺癌扩大根治术。术中发现两个甲状腺病变，故患者明确诊断为肾癌伴甲状腺转移和甲状腺乳头状癌。此外，在甲状腺周围疏松结缔组织中还发现了两个肾癌转移的结节和一个甲状腺癌转移的淋巴结病变。
甲状腺转移合并甲状腺癌和肾癌罕见同时发生，原发肿瘤难以识别。虽然临床检查方法不断更新，但既往病史和体检仍然非常重要。
