cronkhite-canada syndrome (ccs) is a rare, non-familial disorder of unknown etiology associated with alopecia, cutaneous hyperpigmentation, gastrointestinal polyposis, onychodystrophy, diarrhea, weight loss and abdominal pain.the prevalence ofâ gastrointestinal malignancy in ccs patients is about 13%, and especially is high in colorectal and gastric areas; 5 year mortality rate is 55%. in this ...

Attenuated familial adenomatous polyposis (AFAP) is a subtype of a condition known as familial adenomatous polyposis [2] (called FAP or classic FAP). People with FAP or AFAP will have an increased number of adenomatous colon polyps during their lifetime and an increased risk of developing colorectal cancer [3]. An adenomatous polyp is a lump filled with the cells that make mucous and line the i...

Endoscopy with multiple biopsies of the upper gastrointestinal tract was repeated yearly over a two to six year period in nine patients with familial polyposis coli from three families. Adenomatous polyps, one to 20 in number and 2-8 mm in size, were detected in the antrum and the first and second duodenal portions in seven patients, while hyperplastic polyps were detected in four patients in t...

BACKGROUND & AIMS An attenuated form of familial adenomatous polyposis has been described, but the phenotype remains poorly understood. METHODS We performed genetic testing on 810 individuals from 2 attenuated familial adenomatous polyposis kindreds harboring an identical germline adenomatous polyposis coli gene mutation. Colonoscopy was performed on mutation-positive persons. RESULTS The d...

Familial adenomatous polyposis (FAP) is a well-known autosomal dominant disorder characterized by the formation of multiple adenomatous polyps of the colon. Gardner's syndrome is a variant of familial polyposis coli, and both can be associated with colonic or extracolonic benign and/or malignant tumors. It has been widely recognized that an adenocarcinoma of the colon develops in virtually all ...

Monoclonal antibodies raised by synthetic peptide immunisation were used to determine the distribution of the protein product of the c-myc gene by immunocytochemical staining of archival wax embedded material from patients with familial adenomatous polyposis. Polyps from 18 cases of familial adenomatous polyposis, 10 of whom had developed malignant change, and 30 normal control colonic biopsy s...

Familial aggregation of diseases potentially associated with metabolic syndrome (diabetes mellitus, hypertension, and cardiovascular diseases) was assessed in a colonoscopy-based case-control study of colorectal neoplasia in Toronto and Ottawa, Canada, in 1993-1996. Each familial disease was analyzed by logistic regression using generalized estimating equations. Case probands had incident adeno...

Fundic gland polyps (FGPs) are the most common type of gastric polyps (up to 50%). They are found in up to 0.8-1.9 % of the general population, and in 40-84 % of the patients suffering from familial polyposis syndromes. They might be sporadic or associated to polyposis syndromes. When the former, they should be considered exclusively benign lesions, and possibly related to the chronic use of pr...

Since then, case reports and family histories have been eagerly studied, and it has become appa ren t that m a n y pat ients afflicted wi th this disease have a tendency to develop adenocarc inoma in one or more polyps before they have a t ta ined the age of 50 years. 1~ I t was no t felt, 1, 4 however, tha t this pro...
