Abstract
This chapter reviews polyps and polyp-like lesions encountered in the small intestine, which are, in essence, non-neoplastic. First Brunner's gland hyperplasia, Brunner's gland hamartoma and peri-ampullary myo-epithelial hamartoma are discussed. Next Peutz-Jeghers polyp and juvenile polyp are reviewed, including the hereditary autosomal dominant syndromes Peutz-Jeghers syndrome and juvenile polyposis, of which these lesions are the phenotypic hallmarks. Yet another polyposis syndrome with unknown aetiology that is extremely rare, Cronkhite-Canada syndrome, is described and, lastly, pyogenic granuloma, occasionally found in the small intestine, is briefly discussed. Although it may be present as a polyp in the small intestine, inflammatory fibroid polyp is considered in the chapter on stromal tumours of the small intestine.
