Abstract
|
|
|
|
Hyperplastic polymp is generally considered as a small, asymptomatic, benign natured polyp. Here, we present a rare case of a hyperplastic polyp, which is very large and in- duces gastric intussusceptions. In addition, after surgery, histopathologic examination confirmed hyperplastic polyp, which contains focal adenocarcinoma. Both the gastric intussuscepted condition itself and the leading tumor, intraepithelial adenocarcinoma arising in the hyperplastic polyp, are extremely exceptional. To the best of our knowl- edge, this is the first reported case of a giant hyperplastic polyp, which causes gastric intussusceptions, and harbored an intraepithelial adenocarcinoma.
