We report an unusual case of a polyp arising from ectopic gastric mucosa in the duodenum. The polyp demonstrated both hyperplastic and adenomatous proliferation. Adenomatous proliferation in a duodenal polyp arising from ectopic gastric mucosa is, to our knowledge, unique. The areas of adenomatous change were morphologically indistinguishable from those of adenomatous polyps arising in the stomach; hence, the adenomatous change observed in this polyp was regarded as a neoplastic process.
我们报告了一例罕见的十二指肠异位胃黏膜息肉病例。该息肉表现出增生性和腺瘤性增殖。据我们所知，由异位胃黏膜引起的十二指肠息肉中的腺瘤性增殖是独一无二的。腺瘤性改变区域在形态上与胃内发生的腺瘤性息肉无法区分；因此，该息肉中观察到的腺瘤性改变被视为一种肿瘤形成过程。
