The malignancy of gastrointestinal carcinoids is dependent on localisa
tion and size of the tumor. Tumors of the small bowel seem to have a t
issue infiltration depth and extension independent of the primary tumo
r size. We give a case report of a patient with a carcinoid tumor in t
he terminal ileum with a dia meter of 5 mm and a tissue infiltration d
epth to submucosa. Based on the immunohistochemical investigation of l
ymphnode metastases for little, accidentally found carcinoids in the i
leum a hemicolectomy with wide mesenteric lymph resection is necessary
.
