Brunner's gland adenoma is a rare tumor of the duodenum and might also be an unusual cause of gastrointestinal bleeding or obstruction. The pathogenesis of Brunner gland hamartoma of the duodenum is unknown. We report two cases of Brunner's gland adenoma. Surgical resection was carried out because the tumor size was big in both cases and one accompanied with bleeding. Pathological examination revealed submucosal nodular hyperplasia of the Brunner's glands.
布伦纳腺腺瘤是一种罕见的十二指肠肿瘤,也可能是胃肠道出血或梗阻的不寻常原因。十二指肠布伦纳腺错构瘤的发病机制尚不清楚。我们报告两例布伦纳腺腺瘤。由于两例肿瘤体积都较大且其中一例伴有出血,故进行了手术切除。病理检查显示布伦纳腺黏膜下结节状增生。
