INTRODUCTION
Since the diagnosis of small renal masses is often a challenge despite improvements in imaging modalities, renal tumor biopsy provides useful information regarding treatment decisions. However, there is no established treatment strategy when renal biopsy shows lymphoid tissue.
CASE PRESENTATION
A 63-year-old woman was referred to our department for the investigation of a small renal mass. Contrast-enhanced computed tomography showed a weakly enhancing mass 39 × 17 mm in diameter in the left kidney. A renal tumor biopsy was performed, and histopathological examination showed lymphoid tissue, but the diagnosis was not confirmed. The tumor was bluntly dissected from the renal capsule via robotic-assisted laparoscopic surgery without renal artery clamping. The pathological diagnosis was non-specific lymphadenitis.
CONCLUSION
We report a rare case of perirenal non-specific lymphadenitis mimicking a solitary renal mass. Non-specific lymphadenitis is a possible differential diagnosis of renal masses.
引言
尽管成像方式有所改进，但小肾肿块的诊断往往仍是一项挑战，肾肿瘤活检可为治疗决策提供有用信息。然而，当肾活检显示为淋巴组织时，尚无既定的治疗策略。
病例报告
一名63岁女性因检查小肾肿块转诊至我科。增强计算机断层扫描显示左肾有一个直径39×17毫米的轻度强化肿块。进行了肾肿瘤活检，组织病理学检查显示为淋巴组织，但诊断未得到证实。通过机器人辅助腹腔镜手术在未夹闭肾动脉的情况下将肿瘤从肾包膜钝性剥离。病理诊断为非特异性淋巴结炎。
结论
我们报告了一例罕见的肾周非特异性淋巴结炎，酷似孤立性肾肿块。非特异性淋巴结炎是肾肿块的一种可能鉴别诊断。
