BACKGROUND
Primary squamous cell carcinoma of the renal parenchyma is extremely rare, only 5 cases were reported.
CASE PRESENTATION
We probably report the fifth case of primary Squamous cell carcinoma (SCC) of the renal parenchyma in a 61-year-old female presenting with intermittent distending pain for 2 months. Contrast-enhanced computed tomography (CECT) revealed hydronephrosis of the right kidney, but a tumor cannot be excluded completely. Finally, nephrectomy was performed, and histological analysis determined that the diagnosis was kidney parenchyma squamous cell carcinoma involving perinephric adipose tissue.
CONCLUSIONS
The present case emphasizes that it is difficult to make an accurate preoperative diagnosis with the presentation of hidden malignancy, such as hydronephrosis.
背景
原发性肾实质鳞状细胞癌极为罕见，仅报道了 5 例。
病例报告
我们可能报告了第五例原发性肾实质鳞状细胞癌（SCC）病例，患者为 61 岁女性，有 2 个月间歇性膨胀性疼痛病史。增强计算机断层扫描（CECT）显示右肾积水，但不能完全排除肿瘤。最终进行了肾切除术，组织学分析确定诊断为肾实质鳞状细胞癌累及肾周脂肪组织。
结论
本病例强调了对于隐匿性恶性肿瘤（如肾积水）的表现，术前准确诊断很困难。
