Cap polyposis is a rare intestinal disorder. Characteristic endoscopic findings are multiple inflammatory polypoid lesions covered by caps of fibrous purulent exudate. Although a specific treatment has not been established, some studies have suggested that eradication therapy for () is effective. We report a case of a 20-year-old man with cap polyposis presenting with hematochezia. Colonoscopy showed the erythematous polyps with white caps from the sigmoid colon to rectum. Histopathological findings revealed elongated, tortuous, branched crypts lined by hyperplastic epithelium with a mild degree of fibromusculosis in the lamina propria. Although eradication was instituted, there was no improvement over six months. We then performed excision of the polyps by endoscopic submucosal dissection (ESD), which resulted in complete resolution of symptoms. ESD may be a treatment option for cap polyposis refractory to conservative treatments. We review the literature concerning treatment for cap polyposis and clinical outcomes.
帽状息肉病是一种罕见的肠道疾病。其特征性的内镜表现为多个炎性息肉样病变，表面覆盖有纤维脓性渗出物帽。尽管尚未确立特定的治疗方法，但一些研究表明，针对（）的根除疗法是有效的。我们报告一例20岁帽状息肉病男性患者，表现为便血。结肠镜检查显示从乙状结肠至直肠有带白色帽的红斑性息肉。组织病理学检查结果显示，隐窝拉长、扭曲、分支，内衬增生上皮，固有层有轻度纤维性结核。尽管进行了根除治疗，但六个月内并无改善。然后我们通过内镜黏膜下剥离术（ESD）切除息肉，症状完全缓解。ESD可能是保守治疗难治性帽状息肉病的一种治疗选择。我们回顾了关于帽状息肉病治疗及临床结果的文献。
