An unusual localization of localized colitis cystica profunda in a 31-year-old man is described. The patient presented as anal bleeding and a protruding mass at the descending colon; the mass was polypoid and was made up of papillary epithelial hyperplasia with downward herniation of glands into the submucosa. Only one similar case involving a descending colon has been reported in the world literature.

BACKGROUD/AIMS: Obesity is a rising problem in industrialized countries. Numerous epidemiologic studies have shown a positive association between obesity and colorectal polyps. There are few studies investigating the association between colorectal adenomatous polyps and body fat composition in Korea. We tried to examine the relationship between body fatness and colorectal adenomatous polyps in health check-up subjects in Korea. METHODS: Six thousand seven hundred and six routine health check-up subjects, who visited our hospital between March 2002 and April 2005 and underwent distal colon examimation with sigmoidoscopy, were enrolled in this study. Among them, colonoscopy was done in 860 patients to evaluate the entire colon. We tried to reveal the relationship between body mass index (BMI) and size, location, number and histopathological type of polyps. BMI was used as an indicator of obesity. RESULTS: The mean value of BMI in total polyp-free group (23.8+/-2.9) was not different from that of the polyp group (24.5+/-2.8, p=0.09). The frequency of rectosigmoid polyps in obese patients (20.4%) was higher than that in non-obese patients (16.0%, p<0.05). The frequency of adenomatous polyp was not different between obese and non-obese group. Number of polyps (> or =4) correlated well with obesity. Moreover, age and triglyceride level in patients with colonic adenoma were significantly higher than in patients without colonic adenom. CONCLUSIONS: This study shows that obesity is not associated with colonic adenomatous polyp in Korean population. However, we observed that obesity may be associated with rectosigmoid colon polyps. Furthermore, age and triglyceride level might be the risk factors of colonic adenomatous polyps in Korean population.

We describe a 58-year-old woman who was incidentally found to have gastric and colonic polyposis, hypoalbuminemia, cutaneous hyperpigmentation and onychodystrophy (Cronkhite-Canada syndrome). Histology of polyps from the stomach showed features of juvenile or retention type (hamartomatous) polyps with Helicobacter pylori (H. pylori) infection. The large pedunculated colonic polyps showed hamartomatous polyps with adenomatous component and polypectomy was performed. After the treatment with H. pylori eradication and omeprazole, the gastric polyposis, hypoalbuminemia and anemia regressed, and endoscopic polypectomy of gastric polyps were performed. After the continuous use of omeprazole for 14 months, the patient showed complete resolution of clinical features of Cronkhite-Canada syndome. The experience of this case suggests that eradication of H. pylori and proton pump inhibitor treatment might be considered in patients with gastric polyposis combined with Cronkhite-Canada syndome.

An optimal treatment for cap polyposis has not been established. Several treatment approaches, including anti-inflammatory agents, antibiotics, immunomodulators, and endoscopic therapy have been described. Surgical resection of the affected colon and rectum may be indicated for patients with persistent disease. Repeat surgery is indicated in cases of recurrence after surgery. However, symptomatic polyposis may still recur, and spontaneous resolution of cap polyposis is possible. We report a case of recurrent cap polyposis complicated with retroperitoneal fibrosis after inadequate low anterior resection with a positive resection margin. Surgical approaches for the treatment of cap polyposis should be carefully considered before treatment.

BACKGROUND/AIMS: Colorectal adenomas that are > or =10 mm have villous histology or high-grade dysplasia, or that are associated with > or =3 adenomas are considered high-risk for metachronous advanced neoplasia. We evaluated the cumulative incidence of metachronous advanced neoplasia according to the total number of high-risk findings detected on baseline colonoscopy. METHODS: This was a retrospective cohort study performed in 862 patients who underwent removal of colorectal adenomas between 2005 and 2009. At least one surveillance colonoscopy had been conducted at Konkuk University Medical Center, Seoul, Korea. RESULTS: The cumulative incidence of metachronous advanced neoplasia in patients with 0, 1, 2, and 3-4 high-risk findings at 1 year were 0.7%, 1.3%, 2.8%, and 8.0%; at 3 years, those were 5.9%, 11.9%, 15.5%, and 24.7%; and at 5 years, those were 8.5%, 18.7%, 26.3%, and 37.2%, respectively. In a multivariate model, the risk of metachronous advanced neoplasia was significantly higher for the multiple high-risk findings group when compared with the 0 high-risk findings group (1 high-risk (+): hazard ratio, 1.86 [95% confidence interval, 1.00-3.44]; 2 high-risk (+): 1.84 [0.88-3.84]; and 3-4 high-risk (+): 3.29 [1.54-7.01]; ptrend=0.020). CONCLUSIONS: The presence of overlapping multiple high-risk findings was associated with an increased risk of advanced neoplasia during surveillance.
