Neuroendocrine tumors of the stomach are rare tumors representing less than 2% of polypoid lesions of the stomach. They are frequently discovered incidentally on endoscopic examination, but they can also cause symptomatic anemia or abdominal pain. Gastric neuroendocrine tumors are derived from enterochromaffin-like cells and they have a known
malignant potential. Usually they are multiple and associated with multiple endocrine neoplasia type 1 or Zollinger-Ellison syndrome, but they can be sporadic as well. Treatment of gastric neuroendocrine tumors can be endoscopic, surgical or systemic. In this article, we present a case report of a male patient, who was surgically treated at the Department of abdominal surgery at the University medical centre in Ljubljana.
