Vascular ectasias, which can be classified as angiodysplasias and arteriovenous malformations (AVMs), accounts for approximately 3% of lower gastrointestinal bleeding. Typically, colonic AVMs are solitary, large, and flat or elevated red lesions on endoscopy. We present an interesting case of a polypoid ulcerated AVM in the transverse colon causing symptomatic anemia, which was resected endoscopically with a resolution of symptoms. Polypoid colonic AVMs are rather rare with only 15 other cases described in the literature. This case highlights the approach to endoscopic management of these lesions.
血管扩张可分为血管发育异常和动静脉畸形（AVM），约占下消化道出血的3%。典型的结肠动静脉畸形在内镜检查中为孤立、较大、扁平或隆起的红色病变。我们报告一例有趣的病例，横结肠息肉样溃疡性动静脉畸形导致症状性贫血，通过内镜切除后症状得以缓解。息肉样结肠动静脉畸形相当罕见，文献中仅描述了其他15例病例。该病例突出了这些病变的内镜治疗方法。
