The patient was a 54-year-old woman who presented to our hospital with right lower abdominal pain and bloody stools. Colonoscopy revealed an elevated lesion, 10 mm in size, in the terminal ileum, that appeared to be like a submucosal tumor. A diagnosis of carcinoid tumor was made by biopsy. Because of the high incidence of lymph node metastasis by carcinoid tumors of the ileum, laparoscopic ileocecal resection was performed instead of endoscopic removal of the tumor. Postoperative histopathological examination demonstrated like a submucosal tumor without muscle layer invasion (sm), but despite the small size of the tumor, a lymph node metastasis was detected at the base of the ileocolic artery. Intubation of the terminal ileum during colonoscopy enabled detection of the tumor in this patient.
