【 摘 要 】

Introduction 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. Case presentation 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. Conclusion 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.
