Inflammatory Fibroid Polyps of the Intestine
American Journal of Clinical Pathology, 1984The clinical and pathologic features of 64 inflammatory fibroid polyps of the large and small bowel in 63 patients are reported. Six of the lesions in the small bowel were studied by electron microscopy. Follow-up information was obtained from 39 patients. The lesion was always benign, occurred at all ages, and had a world-wide distribution.

The patient with multiple intestinal polyps
Best Practice & Research Clinical Gastroenterology, 2007The management of patients with multiple intestinal polyps may be difficult and greatly depends on the correct classification. Polyposis syndromes account for less than 1% of newly diagnosed colorectal cancers. In addition the risk for extracolonic cancer is increased in most syndromes. Here we report the case of a difficult patient with severe gastric

The American Journal of Surgery, 1951
Abstract 1. 1. Polyps of the large intestine are frequent. They are usually single but increase in number until in certain patients they become uncountable. 2. 2. Any polyp may develop into carcinoma. The more polyps, the greater tendency for carcinoma to form. 3. 3. All polyps should be removed. 4. 4.

In the discussion of the article by Beckwith et al, 1 van Heerden was "... unaware of any biliary factors or any studies..." that sought to identify a factor that caused these polyps to develop. We have conducted several such studies, and

Serrated polyps of the large intestine
Seminars in Diagnostic Pathology, 2005Serrated polyps of the large intestine comprise a family of lesions bearing some histological similarities, including an overall serrated configuration caused at least in part by inhibition of apoptosis by mutations in one of two genes. Over the past decade, it has become apparent that these lesions can be subdivided by histological criteria into ...

Sonographic diagnosis of intestinal polyps in children
Pediatric Radiology, 2008Although colonoscopy is the modality of choice for the diagnosis of intestinal polyps, sonography may be the first diagnostic modality in the evaluation of children with this pathology. Graded compression sonography of the small and large bowel may be useful in diagnosing intestinal polyps.

Hamartomatous Polyps in the Intestine of Two Dogs
Journal of Comparative Pathology, 1994Partly obstructing, proliferative mucosal masses in the small intestine of two dogs were shown histologically to be hamartomatous polyps. They were characterized by an extension of smooth muscle from the muscularis mucosae into the lamina propria of the lesion. This is the first report of such lesions in domestic animals.
