For regression analysis, LSTs with an adenomatous
pit pattern, high-grade dysplasia histology, or adenocarcinoma histology were significant independent risk factors for piecemeal resection after EMR (OR 14.036, 95% CI 2.882-68.360, p=0.001; OR 3.418, 95% CI 1.129-10.346, p=0.030; and OR 12.979, 95% CI 2.377-70.855, p=0.003, respectively).
The current clinical guidelines for the testing and management of hereditary GI cancers from the American College of Gastroenterology (2015) recommend genetic testing in individuals with more than 10 cumulative colorectal adenomatous
Previous reports have described adenomatous
change in juvenile polyps, but predominantly in patients with multiple polyps or juvenile polyposis rather than solitary juvenile polyps.

Among the adenomatous
polyps 29 cases were tubular adenomas, 12 cases were tubulovillous adenomas and 6 cases were villous adenomas.
They noted that CRC among White patients was similar to that seen in western countries with respect to incidence' distribution, sex ratio, and synchronous lesions; in the African population' CRC was uncommon and presented late with advanced disease, with absence of synchronous adenomatous
polyps and cancers and absence of diverticular disease, and was associated with a high fibre and low meat and fat diet.
Most common neoplastic polyps are adenomas or adenomatous
polyps, which arise due to dysplastic proliferation and have a potency to progress to cancer.
Same result was seen with adenomatous
goiter and benign cystic lesion.
Attenuated familial adenomatous
polyposis (AFAP), or oligopolyposis, is characterized by an older age of onset, usually between the ages of 40 to 70, with a fewer number of colorectal adenomas (< 100) and a predilection to the proximal colon [1, 3, 5].
Of the 80 patients, 22 had no adenomatous
nodule in the prostatic TZ (group A), with a median PV of 23.1 ml (Table 1).
Basil Morson from London, United Kingdom, perhaps the best known and revered gastrointestinal pathologist of the mid to late twentieth century, used the term metaplastic polyp in 1962 for what we now call hyperplastic polyps in order to distinguish them from true adenomatous
