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.
