Lymphoceles are sometimes formed after pelvic lymph node dissection. However, recurrence at lymphoceles has not been reported previously. Here, we report a case of rapid prognosis of the recurrence at a lymphocele after nephroureterectomy.
A 78-year-old man underwent retroperitoneoscopic radical nephroureterectomy with pelvic lymphadenectomy for left ureteral urothelial carcinoma. The histopathological diagnosis was high-grade invasive urothelial carcinoma with squamous differentiation. Follow-up computed tomography at 3 months postoperatively showed a lymphocele with a small solid component, in the left pelvic region. At 7 months postoperatively, he presented with severe fatigue, and computed tomography showed a solid tumor had replaced the lymphocele. Computed tomography-guided biopsy was performed and histopathological diagnosis was squamous cell carcinoma.
This report provides support for possible recurrence at the lymphocele after nephroureterectomy. If lymphocele occurs after surgery for malignant disease, it is recommended to follow up with the possibility of recurrence in the lymphatic cysts in mind.
盆腔淋巴结清扫术后有时会形成淋巴囊肿。然而，此前尚未有淋巴囊肿复发的报道。在此，我们报告一例肾输尿管切除术后淋巴囊肿快速复发的病例。
一名78岁男性因左输尿管尿路上皮癌接受了后腹腔镜根治性肾输尿管切除术及盆腔淋巴结清扫术。组织病理学诊断为高级别浸润性尿路上皮癌伴鳞状分化。术后3个月的随访计算机断层扫描显示左盆腔区域有一个伴有小实性成分的淋巴囊肿。术后7个月，他出现严重疲劳，计算机断层扫描显示一个实性肿瘤取代了淋巴囊肿。进行了计算机断层扫描引导下的活检，组织病理学诊断为鳞状细胞癌。
本报告为肾输尿管切除术后淋巴囊肿可能复发提供了依据。如果在恶性疾病手术后出现淋巴囊肿，建议在随访时考虑淋巴囊肿复发的可能性。
