Skip metastasis in colorectal cancer consists of about 10% of lymph node metastases. We report a rare long-term surviving patient of skip metastasis to lateral nodes after lymph node dissection. A forty-two years old female received anterior resection for advanced rectosigmoid cancer. Because pathological stage of the patient was stage IIIa (T3N1M0), standard adjuvant chemotherapy was provided. Serum CEA increased just two years after the first operation. PET scan showed abnormal FDG uptake in lymph nodes along the aorta. Lymph nodes along the inferior mesenteric artery (IMA), bilateral common iliac artery and aorta were dissected. There were metastases to nodes along the common iliac artery but no metastasis along the IMA was observed. So we diagnosed it as skip metastasis. The patient is still alive without any metastasis after 6 years from the second operation.
