A 67-year-old woman with anemia was referred to us for further study. A colonoscopy exhibited multiple tumors(tub1)in the transverse and sigmoid colon(two regions)and rectum. Contrast-enhanced CT revealed no apparent distant and lymph node metastases. Thus, subtotal colectomy with D3 lymph node dissection was performed. Pathologically, the tumor was diagnosed as pStage Ⅱand pStage 0. After surgery, the patient had no recurrence for 8 months. We herein report a rare case of four synchronous colorectal carcinomas that were successfully treated.
