Sessile: This is a flat or dome-shaped growth that sits on the colon's lining.Sessile polyps are more likely to become cancerous, in part because they are ...

Colon polyps are protrusions occurring in the colon lumen most commonly sporadic or as part of other syndromes. Polyps are classified as diminutive if 5 mm in diameter or less, small if 6 to 9 mm, or large if they are 1 cm in diameter or more. Polyps can be depressed, flat, sessile or pedunculated. Few polyps arise from submucosa including lipomas, carcinoids or lymphoid aggregates. Most ...

Discussion. Several other studies have confirmed that examination of deeper levels improves diagnostic accuracy in ND CR "polyp" biopsy specimens 8, 10, 12, 15, 16 and subsequently improves patient care. However, we are not aware of another study that compares diagnostic change and adenoma detection rates on examination of deeper levels in ND CR biopsy specimens from 2 different ...BACKGROUND AND AIMS A histopathological feature considered indicative of ulcerative colitis (UC) is the so-called basal lymphoid aggregates. Their relevance in the pathogenesis of UC is, however, unknown. We have performed a comprehensive analysis of the immune cells in these aggregates most likely corresponding to the lymphoid follicular hyperplasia also described in other colitides.

What is a lymphoid aggregate polyp? A lymphoid polyp is an often benign, focal proliferation of gut associated lymphoid follicles. Lymphoid polyps are rarely found in adults and are usually found in terminal ileum or rectum. These polyps are usually asymptomatic though possible association with development of malignant lymphoma has been described.
