Even the term familial adenomatous polyposis does not fully describe the defect because les...
Gardner syndrome (GS) is a group of diseases manifested as familial adenomatous polyposis accompanied by characteristic jaw lesions. The documented prevalence of Gardner syndrome varies from 1: 8,300 to 1: 16,000 live births in varying literatures [1]. The syndrome associated intestinal polyps have a 100% risk of malignant transformation [2]. Early identification and surgical intervention of th...
Two sisters with Turcot's syndrome, in which malignant cerebral neoplasms are associated with colonic polyposis, are presented. Cases reported in the literature, including some familial cases, have also been analysed. In familial cases, sex was unrelated to the occurrence of this disease and it was found only among siblings of the same parents and not in other members of the family. There was c...
the inherited polyposis syndromes and colorectal carcinoma. Four patients are reported, to illustrate the wide spectrum of colonic polyps which may occur in multiple form in adults. Included are unusual cases of metaplastic and-juvenile polyposis. The subject is reviewed, and the need for accurate histological diagnosis is stressed. The possibility that the difference between familial adenomato...
Juvenile polyposis syndrome (JPS; MIM 174900) is an autosomal dominant condition with incomplete penetrance characterized by hamartomatous polyps of the gastrointestinal tract and a risk of gastrointestinal cancer. Gastrointestinal hamartomatous polyps are also present in Cowden syndrome (CS; MIM 158350) and Bannayan-Zonana syndrome (BZS; also called Ruvalcaba-Myhre-Smith syndrome; MIM 153480)....

BACKGROUND The histogenesis of human colorectal hyperplastic polyps and colorectal adenomas is poorly understood even now.
