 症例は66歳女性.上部消化管内視鏡にて十二指腸第2部に有茎性ポリープ様腫瘤を認めた.生検施行時に内容液の漏出が認められ,嚢胞性ポリープとして内視鏡的切除術を施行した.腫瘤は基部にブルンネル腺過形成を認め,嚢胞壁はブルンネル腺細胞から成り,嚢胞形成を主体としたブルンネル腺過形成と診断した.1990年以降のブルンネル腺腫瘍本邦論文報告例に自験例を加えた62例を組織学的に分類し,検討を加え報告した.

A pedunculated mass arising from the second portion of the duodenum was detected in a 66-year-old woman during a follow-up endoscopic examination after treatment of a gastric and duodenal ulcer. The mass was a soft, 3cm-sized, polypoid projection into the lumen and was overlaid by intact duodenal mucosa. When biopsied, clear fluid was exuded from the polyp. Endoscopic resection was performed with a preoperative diagnosis of cystic polyp of the duodenum. The resected specimen revealed a simple submucosal cyst containing clear mucinous fluid, and Brunner's gland hyperplasia was observed in the stalk of the polyp. The wall of the cyst was lined with a single layer of columnar cells, and it appeared to represent cystic change of Brunner's gland hyperplasia. In addition to our own case, 61 cases of Brunner's gland tumor have been reported in Japan in the last decade. We review them from the standpoint of cystic change, and have classified them into four histological categories.
