Familial adenomatous polyposis (FAP) is characterised by hundreds of colorectal adenomas. Endocrine neoplasms have occasionally been reported, as have gastric polyps, which are usually hamartomatous in the fundus of the stomach and adenomatous in the antrum. A 57 year old man with colorectal, gastric, and periampullary adenomatous polyposis, in association with three bilateral adrenocortical ad...
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...
gastric cancer (gc) is the second most common cancer in the world and a leading cause of cancer-related mortality. methylation of promoter cpg islands (cgis) belonging to tumor suppressor genes causes transcriptional silencing of their corresponding genes leading to carcinogenesis and other disorders. adenomatous polyposis coli (apc) a tumor suppressor gene is inactivated by methylation of prom...
The term 'polyposis coli' applies to a condition of multiple polyps of the large intestine and is used synonymously with 'familial polyposis' and 'multiple adenomatosis'. The latter name emphasizes the fact that the individual polyps of this disease in no way differ from adenomas observed as solitary lesions. The object of this paper is to describe the histopathology, clinical features, and fam...

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...
Most hamartomatous polyps in the stomach occur in patients with adenomatous polyposis coli and dysplasia. The authors report a case of a 57-year-old man without prior history of polyposis coli who presented with adenocarcinomas derived from hamartomatous polyps in the stomach. The patient underwent a radical subtotal gastrectomy with Billroth I anastomosis. Pathology revealed adenocarcinomas wi...
