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.

OBJECTIVE: To investigate the features and correlation of nasal inverted papilloma complicated with polyps. METHOD: Twelve patients diagnosed as nasal inverted papilloma complicated with polyps were studied. The pathological specimens were taken from the surface, core and base of papilloma and sinus in every patient. Through comparing pathological findings, the features and correlation of nasal inverted papilloma complicated with polyps were evaluated. RESULT: In most cases, nasal inverted papilloma was located in the core and base of the mass, while the polyps were located in the surface of the mass. CONCLUSION Nasal inverted papilloma complicated with polyps may result from long-term inflammation that occurred in the surface of the epithelia of superficial papilloma. Therefore, the occurrence of neoplastic disease in core should be alerted in unilateral nasal polyp case.

Objective: To compare the clinical characteristics and plasma inflammatory markers levels in different endotypes of chronic rhinosinusitis with nasal polyps (CRSwNP), and to explore the plasma biomarkers associated with endotypes of CRSwNP. Methods: A total of 74 CRSwNP patients (male/female: 41/33; average age: 40 years) and 40 control subjects underwent septoplasty in Tongji Hospital from January 2015 to December 2017 were enrolled in this study. The demographic and clinical features of all subjects including age, gender, past history, visual analogue scale (VAS) and CT scores were recorded. Patients with CRSwNP were divided into Eos^highNeu^high, Eos^highNeu^low, Eos^lowNeu^high and Eos^lowNeu^low four endotypes according to the eosinophil (Eos) percentage and neutrophil (Neu) count of nasal polyps tissue. Preoperative blood routine was performed and the levels of 27 biomarkers in plasma were measured by Bio-Plex suspension chip method. The clinical characteristics and the level of serum biomarkers of patients with different endotypes were compared. SPSS 18.0 software was used for statistical analysis. Results: There was no difference in the clinical features including gender ratio, age, course of disease, VAS score, endoscopy and CT score among Eos^highNeu^high, Eos^highNeu^low, Eos^lowNeu^high and Eos^lowNeu^low CRSwNP patients. Compared with Eos^lowNeu^high and Eos^lowNeu^low CRSwNP patients, patients with Eos^highNeu^high and Eos^highNeu^low endotype demonstrated a higher prevalence of atopy, allergic rhinitis and asthma comorbidity, and increased peripheral blood eosinophil absolute count and percentage (all P<0.05). However, there was no significant difference between Eos^highNeu^high and Eos^highNeu^low CRSwNP. Plasma levels of all 27 mediators including type 1 cytokines (IL-12 and IFN-γ), type 2 cytokines (IL-4, IL-5 and IL-13), type 3 cytokines (IL-17A), pro-inflammatory cytokines (IL-6 and TNF-α) and tissue remodeling-related markers (bFGF, VEGF and PDGF-BB) demonstrated no significant difference among all endotypes of CRSwNP (all P>0.05). Conclusions: Eos^high and Eos^low CRSwNP patients display significant differences regarding the prevalence of atopy, allergic rhinitis and asthma comorbidity, peripheral blood eosinophil absolute count and percentage, but the clinical characteristics, blood cellular and biological markers can not effectively distinguish four endotypes of CRSwNP. Further studies are warranted to dig out the potential objective, convenient and reliable markers associated with endotypes in patients with CRSwNP.

Ulcerative colitis is an idiopathic chronic inflammatory bowel disease and its incidence in Korea has rapidly increased over the past two decades. Since ulcerative colitis is associated with increased risk for colorectal cancer, annual or biannual colonoscopy with four quadrant random biopsies at every 10 cm segments has been recommended for surveillance of colitic cancer in patients with long standing left-sided or extensive colitis. Recent epidemiologic data and meta-analysis suggest that the increment of colorectal cancer risk in ulcerative colitis was not larger than that of previous studies. Moreover, in addition to the extent and duration of colitis, other risk factors such as family history of colorectal cancer, primary sclerosing cholangitis, stricture, pseudopolyps, and histologic severity of inflammation have been recognized. As a result, updated guidelines provide surveillance strategies adjusted to the individual patient's risk for colitic cancer. Regarding surveillance method, target biopsy under panchromoendoscopy is preferentially recommended rather than random biopsy.

Cowden's disease, also known as various hamartomatous malformations of multiple organs, is a rare autosomal dominant disorder. The most important feature of Cowden's disease is its frequent association with malignant neoplasm, particularly in the breast and thyroid gland. Cowden's disease with malignant neoplasms, is quite rare in Korea so far. We report a case of Cowden's disease associated with breast cancer in a 41-year-old female who underwent routine health cheek-up.

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.
