%X Os tumores neuroend車crinos gastrointestinais s o neoplasias raras. A probabilidade de ocorr那ncia simultanea de tumores neuroend車crinos g芍stricos e duodenal 谷 baixa. Os autores descrevem o caso de um doente do sexo masculino, 73 anos, com diagn車stico de anemia perniciosa desde h芍 13 anos, submetido a endoscopia digestiva alta por vigilancia. O exame revelou mucosa do corpo g芍strico com aspecto atr車fi co com pequenas p芍pulas e um p車lipo s谷ssil no bulbo duodenal. O exame histopatol車gico mostrou tratar-se de microtumores neuroend車crinos g芍stricos no contexto de gastrite atr車fi ca e um tumor neuroend車crino no bulbo duodenal. Os autores discutem a ocorr那ncia simultanea de tumores neuroend車crinos g芍stricos e duodenal, no contexto de doente com anemia perniciosa, abordando o mecanismo etiopatog谷nico, estrat谷gia de tratamento e progn車stico destas patologias 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
