title: [A Case of Neuroendocrine Tumor of the Ileum Manifesting as Fecal Occult Blood].
abstract: A 42-year-old woman was admitted to our hospital because of a positive fecal occult blood test. Colonoscopy examination revealed an elevated lesion measuring 25mm in diameter at the terminal ileum. A histological diagnosis of neuroendocrine tumor(NET)was made based on biopsy specimens taken from the lesion. Since no apparent distant metastasis other than the ileocolic lymph nodes was noted, laparoscopy-assisted ileocecal resection with regional lymph node dissection was performed. In the resected material, NET(G2)limited to the subserosa layer was present. The NET tested positive for synaptophysin, chromogranin A, and CD56. Metastases in the paraileal lymph nodes was detected. NET metastasis to the ileum is frequent, even if the tumor is small in diameter; therefore, it is necessary to resect the tumor entirely and to dissect the regional lymph nodes.
