Polypoid prolapsing mucosal fold in diverticular disease

M R Ambrosio, B J Rocca, A Ginori, A Barone, M Onorati, S Lazzi
Colonic muco-submucosal elongated polyp is a rare entity (0.39% in an endoscopic polypectomy series). It is an elongated drumstick-shaped lesion characterized by oedematous, loose connective tissue with a dense submucosal layer showing dilation of blood and lymphatic vessels. First described as a polypoid lesion associated with diverticular disease of the sigmoid colon, it was histologically characterized as a separate entity by Kelly in 1991. In that study, the author reported eight cases in which a red or brown mucosal protrusion or polyp were associated with diverticular disease, and described the syndrome as "polypoid prolapsing mucosal folds in diverticular disease"...

BACKGROUND: Inflammatory myoglandular polyp (IMGP) is a rare non-neoplastic polyp of the large bowel, commonly with a distal localization (rectosigmoid), obscure in its pathogenesis. Up till now, 60 cases of IMGP have been described in the literature, but none located in the cecum. CASE PRESENTATION: We report a case of a 53-year-old man who was admitted to our hospital for further evaluation of positive fecal occult blood test associated to anemia. A colonoscopy identified a red, sessile, lobulated polyp of the cecum, 4...

Diverticular disease affects upwards of 50% of the population over the age of 60 years in Western countries and is becoming more common as the population ages. Studies from the 1970s and 1980s related its occurrence to the use of low-fiber diets and to the prolonged colonic transit time and increased intraluminal pressure associated with low-volume stools. Pulsion diverticula (pseudodiverticula) emerge through the thickened circular layer of the muscularis propria of the left colon at points of penetration of the vasa recta that supply the submucosa and mucosa...

The aim of this study was to evaluate findings on CT colonography (CTC) in patients with diverticular disease. In a retrospective analysis of 160 consecutive patients, who underwent CTC and conventional colonoscopy (CC), patients with diverticular disease were retrieved. The CTC images were compared with CC and, if possible, with pathology. Findings on both 2D and 3D images are illustrated with emphasis on diagnostic problems and the possible solutions to overcome these problems. Several aspects of diverticulosis were detected: prediverticulosis (3%); global (55...

A clinicopathological study of polypoid lesions of the lower gastrointestinal tract from 12 patients was undertaken. Clinically, the majority had signs and symptoms of rectal prolapse despite having a variety of other primary diagnoses (e.g. carcinoma of the bowel or diverticular disease). Three patients were asymptomatic. The polyps were more common in females and were usually solitary. Histologically, fibrin 'caps', fibromuscular hypertrophy and obliteration of the lamina propria, goblet cell hypertrophy and serrated tubules were consistently noted...
July 1993: Histopathology
J K Kelly
Redundant or polypoid mucosal folds were found in eight surgically resected sigmoid colons with diverticular disease. Grossly, they were either swellings of mucosal folds or larger, leaflike, smooth-surfaced polyps with broad bases arising from mucosal folds. The number of lesions ranged from one to 11, and when multiple they formed two rows between diverticula. Swollen mucosal folds showed submucosal and mucosal vascular congestion, scanty thrombi, edema, hemorrhage, and hemosiderin deposition. Some were markedly inflamed...
