Cystic lymphangiomas are rare benign tumours and their actual incidence in the colon is unclear. Within the large bowel, these lesions are often submucosal and are incidental findings on colonoscopy.
A 43-year-old man with colonic lymphangioma presented with a 7-month history of abdominal pain and altered bowel habits. Computed tomography showed a cystic mass lesion at the distal descending colon. Colonoscopy revealed a smooth, polypoid mass, initially thought as an inverting diverticulum. He underwent laparoscopic high anterior resection. The pathological analysis revealed the descending colon mass to be a lymphangioma with no evidence of diverticulosis.
There is increasing incidence in lymphangioma due to the increasing accessibility to colonoscopy, particularly for asymptomatic or subacute disease. Although colonoscopic excision, sclerotherapy and use of steroids or fibrin glue have been advocated as possible modes of treatment, surgical excision is still considered to be the treatment of choice.
囊性淋巴管瘤是罕见的良性肿瘤，其在结肠中的实际发病率尚不清楚。在大肠内，这些病变通常位于黏膜下，是结肠镜检查时的偶然发现。
一名患有结肠淋巴管瘤的43岁男性，有7个月的腹痛和排便习惯改变病史。计算机断层扫描显示降结肠远端有一个囊性肿块病变。结肠镜检查发现一个光滑的息肉样肿块，最初被认为是内翻性憩室。他接受了腹腔镜高位前切除术。病理分析显示降结肠肿块为淋巴管瘤，无憩室病证据。
由于结肠镜检查的可及性增加，尤其是对于无症状或亚急性疾病，淋巴管瘤的发病率在上升。尽管有人提倡结肠镜切除、硬化疗法以及使用类固醇或纤维蛋白胶作为可能的治疗方式，但手术切除仍被认为是首选治疗方法。
