Thyroid follicular renal cell carcinoma is a special type of renal cell carcinoma newly recognized in recent years. It has attracted attention because of its unique histology, immunophenotype, and clinical characteristics. It has a very low incidence, and the number of case reports available for review is limited. Moreover, a thyroid mass with type of tumour is rare.
We report a case of a renal mass with a bilateral thyroid mass that was accidentally discovered in a 60-year-old man during physical examination. B-mode ultrasound showed a hypoechoic mass in the middle and lower parenchyma of the right kidney, and computed tomography showed an iso-density shadow tumour in the right kidney. Contrast agents had a significant continuous enhancement effect on the tumour, and the enhancement was not uniform. After partial nephrectomy, pathological analysis was performed to rule out the possibility that the renal tumour was caused by thyroid tumour metastasis. Needle biopsy of the thyroid tumour confirmed that the renal cell carcinoma was not related to the thyroid tumour. The patient was alive at the last postoperative follow-up.
This is the third published case in which thyroid tumour biopsy was performed to confirm that thyroid follicular renal cell carcinoma is not thyroid related.
甲状腺滤泡性肾细胞癌是近年来新认识的一种特殊类型的肾细胞癌。因其独特的组织学、免疫表型和临床特征而受到关注。其发病率极低，可供回顾的病例报告数量有限。此外，伴有肿瘤类型的甲状腺肿块较为罕见。
我们报告一例60岁男性在体检时意外发现的双侧甲状腺肿块合并肾肿块的病例。B超显示右肾中下实质内有低回声肿块，计算机断层扫描显示右肾有等密度阴影肿瘤。造影剂对肿瘤有明显的持续增强作用，且增强不均匀。部分肾切除术后进行病理分析以排除肾肿瘤由甲状腺肿瘤转移引起的可能性。甲状腺肿瘤穿刺活检证实肾细胞癌与甲状腺肿瘤无关。患者在最后一次术后随访时存活。
这是第三例经甲状腺肿瘤活检证实甲状腺滤泡性肾细胞癌与甲状腺无关的已发表病例。
