Materials and methods: The slides with the diagnosis of heterotopic gastric mucosa during 2014-2015, were reviewed, and clinical, histological and endoscopic data was to collected for every case. Results: 45 cases of heterotopic gastric mucosa in duodenum were found, 91.1% were located in duodenum bulb and 73.2%, presenting as polyps in 73.2% of cases. In all cases, parietal cell was identified as main criteria for the diagnosis. Neither Helicobacter pylori nor dysplasia were identified. Conclusions: Our data confirm its non neoplastic nature. Heterotopic gastric mucosa should be taken into account in diagnosis of duodenal polyps. Parietal cells identification in duodenal mucosa is essential in differential diagnosis with peptic duodenitis
