We would report a case of small rectal carcinoid with lymph node metastasis. A 65-year-old woman was referred to us for rectal cancer. We performed a total colonoscopy, and found a submucosal tumor which was located 3cm above the rectal cancer. Anterior resection was performed for the advanced rectal cancer with lymph node dissection including the submucosal tumor. The submucosal tumor was diagnosed as a carcinoid tumor 5mm in diameter. Pathological examination revealed regional lymph node metastasis of revealed this carcinoid. We conclude that this is the smallest reported rectal carcinoid with lymph node metastasis.
