SAIOTE, Joana et al. Simultaneous gastric and duodenal neuroendocrine tumors. J Port Gastrenterol. [online]. 2012, vol.19, n.2, pp.95-98. ISSN 0872-8178.

Gastrointestinal neuroendocrine tumors are relatively rare neoplasms and usually occur singly. The probability of simultaneous occurrence of gastric and duodenal carcinoid tumors is low. The authors report a case of a 73-year old male patient, diagnosed pernicious anemia 13 years ago, who underwent upper endoscopy for surveillance. The examination revealed atrophic gastritis and a polypoid lesion in the duodenal bulb, which was completely excised. Pathological examination revealed gastric microcarcinoids in the context of atrophic gastritis and a neuroendocrine tumor in the duodenal bulb. The authors discuss the simultaneous occurrence of gastric carcinoid tumors and duodenal, in the context of pernicious anemia, addressing the etiopathogenic mechanism, treatment strategy and prognosis of these diseases
