This report describes an unusual case of a symptomatic Brunner's gland adenoma arising in a man in his 40s that underwent robotic transduodenal resection. Initial investigations revealed a polypoidal, submucosal lesion that was found in the first part of the duodenum. Microscopically, there was neither dysplasia nor evidence of adenocarcinoma, suggesting differentials of gastrointestinal stroma tumour and duodenal adenoma. Given the size of the lesion, he underwent a surgical resection. Symptomatic Brunner's gland adenoma is uncommon and should be considered as a differential diagnosis in patients presenting with obstructive symptoms.
