A Case of Rectal Cap Polyposis Cured by Segmental Resection / 대한소화기내시경학회지

ABSTRACT

Cap polyposis is a rare condition, which is characterized by inflammatory polyp located mainly from the rectum to the sigmoid colon with a "cap"-coverage of granulation tissue. A 60-year-old woman with tenesmus, constipation, and abdominal pain visited our hospital. Colonoscopy showed variable sized multiple polypoid lesions limited in high rectum, mainly 10 cm distance from anal verge. No other abnormalities of colonic mucosa were seen beyond this area. Medical treatments including stool softner and oral steroid had a little symptomatic improvement. Because symptoms had been frequently recurred after withdrawal of these medications, surgical resection was intended for diagnosis and curative treatment. Resected specimen showed multiple inflammatory polyps with granulation cap. After the resection, the patient has been good at daily activity without evidence of symptomatic or endoscopic aggravation.
