摘要

CMSEP 是一种大肠息肉，其柄长而宽，外观呈 "蠕虫状"，被正常粘膜覆盖。粘膜下层由水肿和纤维化间质、脂肪组织、扩张的血管和淋巴滤泡组成[1]。粘膜表面的内镜放大图显示，规则的血管呈均匀的蜂窝状，顶部有柔软、可变形的 "褶皱 "和 "回旋"。CMSEP 的确切发病机制尚不清楚。

Colonic muco-submucosal elongated polyp misdiagnosed as an inverted colonic diverticulum.

Colonic muco-submucosal elongated polyp is a large intestine polyp with a long and broad stalk and a "worm-like" appearance which is covered by normal mucosa. The submucosal layer consists of edematous and fibrotic interstitium, adipose tissue, dilated blood vessels, and lymphatic follicles. Endoscopic magnification of the mucosal surface showed a uniform honeycomb pattern of regular colonic muco-submucosal elongated polyp vessels, with soft and deformable "folds" and "gyrus" at the top. The exact pathogenesis of CMSEP is still unclear.
