Annual Review of Medicine, 1985
Carcinoma of the large bowel arises almost exclusively in neoplastic polyps, which are present in 5-10% of the population over age 40. These polyps may be of three histologic types: (a) tubular adenoma (adenomatous polyp), (b) tubulovillous adenoma (villoglandular polyp), and (c) villous adenoma.

Gut, 2020
A 56-year-old man presented with a change in bowel habit to seven loose non-bloody stools a day. He had previously had a sigmoid resection for an endoscopic diagnosis of colonic malignancy in 2015. Histology of the resection specimen, however, had only shown inflammatory polyps, attributed to the accompanying diverticular disease.

Leiomyomatous colonic polyps are rare. We report a patient with an asymptomatic 15-mm submucosal polyp in the sigmoid colon. The tumor was successfully removed by endoscopy. Histopathological examination revealed a leiomyoma originating in the muscularis mucosa.

Journal of Surgical Oncology, 1997
Colon polyps may be single or multiple, noninherited or inherited, histologically may vary from inflammatory, hamartomatous, neurogenic, or adenomatous, and may be benign or malignant. The various recognized syndromes are discussed including their clinical presentation, malignant potential, and associated tumors. Recognition of these clinical syndromes

Endoscopy, 2000
The superiority of colonoscopy to double-contrast barium enema in detecting neoplasia was finally demonstrated in 2000, but colonoscopic surveillance programs are still based on short-term observations and are mostly inadequate, despite the prospective design of the trials. The evaluation of the diagnostic accuracy of virtual colonoscopy is in progress,

Best Practice & Research Clinical Gastroenterology, 2002
Colorectal cancer (CRC) is one of the best studied cancers. It is easily accessible and develops slowly over several years from premalignant lesions (adenomatous polyps) to invasive cancers. The key molecular events in this sequence have been characterized.

Colonic polyps complicating ureterosigmoidostomy
Histopathology, 1980Polypoid tumours of the small and large intestine have been recognized as a complication of the implantation of ureters into the bowel for many years. Some cases could be recurrences of the urothelial tumour which necessitated the original operation or alternatively others may be tumours arising from the bowel epithelium itself.

Acromegaly results from unrestrained secretion of growth hormone and insulin-like growth factor 1 (IGF-1), usually occurring as a result of a pituitary somatotroph adenoma (1).

Transitional Polyps of the Colon
Endoscopy, 1982Fourteen polps with the gross appearance of small hyperplastic (metaplastic) polyps, not exceeding five mm in diameter, were removed from the rectum and the sigmoid colon of patients during colonscopy, and from surgical specimens. At light microscopy they were seen to be composed of apparently normal mucosa. In most cases some hyperplastic (metaplastic)
