Multiple carcinoid tumors of the rectum is rare and the accumulated number of the cases in Japan is 13. Carcinoid tumors less than 10 mm in diameter have little metastasis. A case of multiple carcinoid tumors 9mm in maximal diameter with node metastasis was reported herein. A 64-year-old male with abdominal discomfort visited our hospital. Colonoscopic examination showed several carcinoid tumors of the middle rectum, and low anterior resection was carried out. The resected specimen demonstrated 9 separate carcinoid tumors from the mid-rectum to rectosigmoid colon. Three of 14 examined lymph nodes were found to be metastatic, and all tumors were less than 10 mm in diameter. The patient is doing well 12 months after surgery, without evidence of recurrent or metastatic disease.
