ABSTRACT
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.
