Case Report A 49-year-old man presented with malaise and shortness of breath for 1 month. Physical examination showed pallor. His blood picture showed hypochromic, microcytic anaemia with haemoglobin of 8.3 gm/dl. Colonoscopy [Olympus, Tokyo, Japan] showed a 3.0 cm large pedunculated polyp at 35 cm from the anal verge in the descending colon. An Endoloop [Olympus, Tokyo, Japan] was placed at th...

Juvenile polyps are relatively common polyps that affect predominantly young patients and may occur in isolated, multiple, and/or familial forms. They have been considered to be benign lesions without neoplastic potential, but for patients with multiple juvenile polyposis, the cumulative malignant risk is greater than fifty percents. In patients with a solitary polyp, the risks are minimal, and...

OBJECTIVE To scrutinize all colonic biopsies and document the prevalence and pattern of various colonic diseases amongst the patients presenting at a tertiary care hospital of Western Saudi Arabia. METHODS We examined the record of all colonic biopsies, processed at Histopathology Department of King Abdul Aziz University Hospital; Jeddah from January 2002 to July 2007. RESULTS The colonic b...

Benign tumors of the ureter are rare and most often appear in the form of fibroepithelial polyps [1]. Fibroepithelial polyps represent from 2 to 6% of all benign tumors of the urinary tract [2]. The Authors report on two cases of fibroepithelial polyps of the ureter, which they treated between 1993-2009. One case was presented by acute urinary retention and gross hematuria. In the second case, ...

The patterns of mucosubstances secreted in the normal human colon and rectum, in benign tumours, and in and around malignant tumours of the colon and rectum have been studied. Very little neutral mucosubstance was seen in normal specimens; the secretion in these was made up of sulphated and nonsulphated acid mucosubstances, with the former predominating in the deeper half and the latter in the ...

Congenital polyps of the posterior urethra are rare lesions, and have often been described in boys. The polyps are benign lesion usually lined by a transitional epithelium, but cases of squamous or intestinal metaplasia have been reported.We report a case of a 10 years old boy referred for hematuria and dysuria.The voiding cysto urethrogram revealed a filling defect in the posterior urethra. At...

Antrochoanal polyp was described by Professor Gustav Killian, in 1906, giving a specificity among polyposis; it represents 4-6% of all nasal polyps and displays both analogies and differences with bilateral nasal polyposis. Antrochoanal polyp is a benign lesion originating from the mucosa of the maxillary sinus, growing through the accessory ostium into the middle meatus and, thereafter, protru...

Most colon CAD (computer aided detection) software products, especially commercial products, are designed for use by radiologists in a clinical environment. Therefore, those features that effectively assist radiologists in finding polyps are emphasized in those tools. However, colon CAD researchers, many of whom are engineers or computer scientists, are working with CT studies in which polyps h...

Esophageal fibrovascular polyps are rare, benign, submucosal tumors of the upper digestive tract that usually have an indolent course until the lesion attains a very large size. The most frequent complaints associated with these tumors include dysphagia and foreign body sensation. However, a long pedunculated polyp can regurgitate into the pharynx or oral cavity and cause asphyxia and sudden de...

We have previously reported that the connective tissue stroma of human colon carcinoma contains elevated amounts of decorin, a small proteoglycan involved in the regulation of matrix formation and cell proliferation. These biochemical changes were correlated with increased mRNA levels and general hypomethylation of the decorin gene in human colon cancer DNA. In this report we use a quantitative...
