aim :  the aim of this study was to present the demographic and clinical characteristics of patients with gastric polypoid lesions and to study the histopathologic features of these lesions. background : the frequency of gastric polyps is gradually increasing due to the widespread use of endoscopic examinations. patients and methods : clinical and endoscopic features of 100 gastric polyposis pa...

Patients with longstanding inflammatory bowel disease (IBD) have an increased risk of colorectal cancer. A causal link between chronic inflammation and cancer is well recognized. Precursor lesions include flat dysplasia (intraepithelial neoplasia) and elevated dysplasia, also known as dysplasia-associated lesion or mass (DALM) [1]. A 52-year-old woman with 20-year history of ulcerative colitis ...

An 84-year-old woman with advanced pharyngeal cancer underwent colonoscopy for intermittent rectal bleeding in October 2012. Colonoscopy disclosed two red sessile polyps in the rectum (Fig 1). The larger one was spherical with a smooth surface, measuring approximately 15 mm in diameter (Fig 2). Biopsy showed hyperplastic glands and marked proliferation of smooth muscle cells in the lamina propr...

Genetic variability in DNA repair genes may contribute to differences in DNA repair capacity and susceptibility to cancer, especially in the presence of exposures such as smoking. In a Minnesota-based case-control study of cases with only adenomatous polyps (n = 384), only hyperplastic polyps (n = 191), or both types of polyps (n = 119) versus polyp-free controls (n = 601), we investigated the ...

BACKGROUND In recent years, there has been growing concern about the overuse of colonoscopy (CC). Our objective was to evaluate the incidence rate and cumulative probability of having a potentially inadequate CC (PI-CC, e.g. a CC that was performed earlier that recommended) and the association between the report of a hyperplastic polyp in the baseline CC report and the probability of having a P...

Endoscopic submucosal dissection (ESD) is an effective, safe technique for treating gastric lesions [1]. Hyperplastic polyps have an underestimated risk formalignancy, which has been reported to be 3.7% in 809 lesionsmeasuringmore than 1cm [2]. Thus, complete en bloc resectionwith ESD is an option to avoid local recurrence [3], particularly when hyperplasia is associatedwith dysplasia. We repor...

OBJECTIVES Few studies investigated the isolation of stem cells from pathologically injured dental tissues. The aim of this study was to assess the possibility of isolation of stem cells from pulp polyps (chronic hyperplastic pulpitis), a pathological tissue produced in an inflammatory proliferative response within a tooth. STUDY DESIGN Pulp polyp tissues were enzymatically digested and the h...

BACKGROUND Colorectal perineuriomas are uncommon benign mucosal-based proliferations of mesenchymal cells that express perineurial markers, often associated with colonic crypts displaying a serrated/hyperplastic architecture. The vast majority of cases arise distal to the splenic flexure and have been described as sessile polyps. Using molecular analysis, BRAF mutations have been demonstrated i...

BACKGROUND Obesity increases the risk of colon cancer. It is also known that most colorectal cancers develop from adenomatous polyps. However, the effects of obesity and adipokines on colonic polyp formation are unknown. METHODS To determine if BMI, waist circumference or adipokines are associated with colon polyps in males, 126 asymptomatic men (48-65 yr) were recruited at time of colonoscop...
