INTRODUCTION
Lipomas are the most common non-epithelial benign tumors of the gastrointestinal tract with a reported incidence in the colon of 0.2-4.4%. These lesions are usually asymptomatic with a typical endoscopic finding of a smooth, slightly yellow, circular, polyp that is sessile in most cases, covered with normal colonic mucosa.
AREAS COVERED
There are rare reported cases of alterations of the overlying mucosa such as hyperplasia, atrophy, adenomatous changes, and necrosis.
EXPERT COMMENTARY
We report a rare case of pedunculated colonic lipoma of the transverse colon covered with hyperplastic and ulcerated epithelium easily misdiagnosed as an adenomatous lesion.

涵盖范围
有罕见报道称黏膜表面会发生改变，如增生、萎缩、腺瘤样改变和坏死。

我们报告了一例罕见的横结肠带蒂结肠脂肪瘤病例，其表面覆盖有增生和溃疡性上皮，容易误诊为腺瘤性病变。
