During episodes of chronic inflammation, Mott cells can present as individual cells or clusters or sheets of cells in the lamina propria or accumulate to form aggregates known as Russell body inflammatory polyp, as seen in the patient of severe diverticulosis presenting with Russell body inflammatory polyp [4, 6]. However, why this response is ...
3. Discussion. Colonic lymphoid hyperplasia is a rare condition especially in adults. It can be localized or diffuse nodular hyperplasia or to a lesser extent a solitary polyp [].Polyps are usually sessile and found in the rectum, although they were sometimes reported in the cecum and descending colon [2-4].A case report by Hong et al. documented eighteen cases of rectal lymphoid hyperplasia ...Abstract. "Serrated polyps" is the term used for epithelial lesions of the colon and rectum that have a "sawtooth" pattern on the polyp's surface and crypt epithelium. The so-called serrated pathway describes the progression of sessile serrated adenomas and traditional serrated adenomas to colorectal cancer. Said pathway is well recognized as ...An intimate admixture of lymphoid aggregates and columnar epithelial glands of inverted lymphoglandular polyp resembles lymphoglandular complex [5, 6]. Lymphoglandular complex is a normal structural entity of the large bowel and it acts as a local receptor of antigenic material for future immune recognition.In a polyp identified during screening, a small area with high-grade dysplasia within the lesion is enough to define the entire high-grade lesion. In other contexts, it is useful to report the presence of both dysplasia pictures. ... HPs, inflammatory polyps, prolapse-type polyps, and lymphoid aggregates, with a high risk of developing CRC ...Thirty polyps were excluded from the study because the pathological report was SSP (n=3), normal tissue or lymphoid aggregate (n=25) or faecal material (n=2); one video was excluded because it was corrupted and two had frames with multiple polyps. Accordingly, 125 polyp videos were evaluated using the AI model.
