Abstract

Introduction

Local recurrence for upper tract urothelial carcinoma typically occurs within 2 years post-surgery. We report a rare case of retroperitoneal recurrence as squamous cell carcinoma 10 years after nephroureterectomy.

Case presentation

A 67-year-old female was referred to our urology department for a left ureteral tumor. The surgical specimen of the laparoscopic left nephroureterectomy revealed urothelial carcinoma at the pT3 stage. Ten years post-nephroureterectomy, magnetic resonance cholangiopancreatography revealed a mass lesion in the left retroperitoneum, a computed tomography-guided biopsy revealed squamous cell carcinoma. Despite suspected distant metastases of other organ tumors, examinations such as digestive endoscopy and bronchoscopy did not reveal any tumor lesions. The patient was diagnosed with recurrent invasive urothelial carcinoma as a pathological feature of squamous cell carcinoma.

Conclusion

The decision-making process for treating malignant tumors, such as in cases with recurrence as squamous cell carcinoma, can be challenging.

肾输尿管切除术后10年腹膜后复发为鳞状细胞癌一例。

上尿路上皮癌的局部复发通常发生在术后2年内。我们报告一例罕见的肾输尿管切除术后10年腹膜后复发为鳞状细胞癌的病例。病例介绍：一位67岁女性因左侧输尿管肿瘤被转介至泌尿科。腹腔镜左肾输尿管切除术的手术标本显示pT3期尿路上皮癌。肾输尿管切除术后十年，磁共振胆管造影显示左侧腹膜后肿块病变，计算机断层扫描引导活检显示鳞状细胞癌。尽管怀疑有其他器官肿瘤的远处转移，但消化道内窥镜和支气管镜检查未发现任何肿瘤病变。患者被诊断为复发性侵袭性尿路上皮癌，作为鳞状细胞癌的病理特征。结论：恶性肿瘤的治疗决策过程，如复发的鳞状细胞癌，可能是具有挑战性的。
