Colorectal polyps are an important albeit uncommon cause of rectal bleeding in children. Colonoscopy promotes both rapid and accurate diagnosis and the opportunity for immediate therapeutic polypectomy. A 10 year audit of polyps diagnosed and treated endoscopically has been undertaken in the children's endoscopy unit. Twenty nine polyps were diagnosed from 730 colonoscopies; 24 were juvenile, t...

AIMS To study the expression of HLA-DR antigen in the different histological types of gastric polyps. METHODS Ninety five cases of gastric polyps were histologically classified and examined for the presence of Helicobacter pylori, and for degree and type of inflammation. Further sections were stained immunohistochemically for HLA-DR antigen expression in the epithelium using a monoclonal anti...

In children, colorectal polyps most commonly present with rectal bleeding. The aim of this study was to establish some correlations between clinical, endoscopic/ histopathological aspects and therapeutic options in pediatric colorectal polyps. The experimental group included 253 children aged between 1 and 18 years, patients being included based on the presence of rectal bleeding associated wit...

PURPOSE Nasal polyposis is a chronic inflammatory disease of the upper airways often associated with asthma and characterized by markedly increased numbers of eosinophils, Th2 type lymphocytes, fibroblasts, goblet cells and mast cells. Previous studies have shown elevated levels of thymic stromal lymphopoietin (TSLP) in atopic diseases like asthma, atopic dermatitis and mainly in animal models ...

Antrochoanal polyps are benign lesions originating from the mucosa of the maxillary sinus. Nasal obstruction and rhinorrhea are their main symptoms. Their endoscopical and radiological appearance makes them relatively easy to diagnose. These polyps are usually presented unilaterally, although bilateral presentation is also possible. We described two cases of atypically giant antrochoanal polyps...

Background: In western countries with high prevalence of colorectal cancers, colonic polyps are usually adenomatous. There are few studies from Iran regarding to the predominant type of polyps in colorectal area. Objectives: We conducted this retrospective study to evaluate the predominant colorectal polyps in our center as the largest referral center of the South region of Iran. Material and M...

Inflammatory polyps are relatively common in patients with inflammatory bowel disease. The term giant inflammatory polyposis is used to describe inflammatory polyps greater than 1.5 cm in any dimension. Their clinical presentation can be varied, ranging from asymptomatic, with incidental detection on radiological or endoscopic testing, to symptomatic, with rectal bleeding and colonic obstructio...

cronkhite- canada syndrome (ccs) considered as a rare and non-hereditary disorder. gastrointestinal polyposis and diarrhea along with some extra signs and symptoms such as hypoproteinemia, and epidermal manifestations are recognized in this syndrome. the pathophysiology of this syndrome is not completely understood and it seems that inflammatory processes may be involved. we present a 50 year-o...

Nasal polyp is a chronic inflammatory disease affecting about 1–4% of the general population. polyps are fleshy benign growth that develop in mucosal lining nasal passage and paranasal sinuses. Polyps vary size having shining pink colour shaped like grapes. The exact etiology remains unclear but it known to have associations with allergy, asthma, infection. common features obstruction, anosmia,...
