A 67-year-old man underwent laparoscopic partial left nephrectomy for renal cell carcinoma 2.5 years ago. CT showed a well-defined 3 cm mass with contrast effect bordering on the descending colon, and PET-CT showed an accumulation of SUVmax 6.01 in the same area. Colonoscopy revealed a submucosal tumor-like mass in the descending colon. The patient was diagnosed with a local recurrence of renal cell carcinoma and invasion of the descending colon, and laparoscopic colectomy was performed. The excised specimen was a pale yellowish submucosal tumor measuring 4.5×3.8 cm, which was histologically diagnosed as metastasis of clear cell renal cell carcinoma. Surgical resections for metastases of renal carcinoma have been reported and expected prolong survival. We report a case of laparoscopic colon resection for recurrence of descending colon metastasis of renal cell carcinoma.
2.5年前，一名67岁男性因肾细胞癌接受了腹腔镜下左半肾切除术。CT显示一个边界清晰的3厘米肿块，与降结肠相邻，增强扫描有强化表现，PET-CT显示同一区域SUVmax为6.01的放射性浓聚。结肠镜检查发现降结肠有一个黏膜下肿瘤样肿块。该患者被诊断为肾细胞癌局部复发并侵犯降结肠，遂行腹腔镜结肠切除术。切除标本为一个淡黄色黏膜下肿瘤，大小为4.5×3.8厘米，组织学诊断为透明细胞肾细胞癌转移。已有关于肾癌转移手术切除的报道，且预期可延长生存期。我们报告一例腹腔镜下结肠切除术治疗肾细胞癌降结肠转移复发的病例。
