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.

介绍

脂肪瘤是胃肠道最常见的非上皮性良性肿瘤，据报道在结肠中的发生率为0.2–4.4％。这些病变通常是无症状的，典型的内窥镜检查显示为平滑的，略带黄色的圆形息肉，多数情况下是无梗的，被正常的结肠粘膜覆盖。

覆盖区域

鲜有报道上层粘膜改变的案例，如增生，萎缩，腺瘤改变和坏死。

专家评论

我们报道了罕见病例的横结肠结肠有蒂的结肠脂肪瘤覆盖着增生和溃疡的上皮，很容易被误诊为腺瘤性病变。
