If adjusted for surface area, all types of adenomas have the same potential to become cancerous.Ĭopyright © 2023, StatPearls Publishing LLC. Tubular adenomas are the most common type of colonic adenomas, comprising a prevalence of more than 80%.Īlthough villous adenomas are more likely to become cancerous, this reflects the fact that they generally have the largest surface area due to their villous projections. A tubulovillous adenoma is referred to as an adenoma with both features. This type of polyp has the highest risk of turning into. Background and study aims Foveolar-type adenoma is described as a very rare tumor that occurs in individuals without Helicobacter pylori (HP) infection and diagnosed as adenocarcinoma in the Japanese Classification of Gastric Carcinoma (JCGC). Villous adenoma: Makes up 15 of the polyps found in the colon. If they are found early, they can be removed during a colonoscopy. A polyp with more than 75% villous features, i.e., long finger-like or leaf-like projections on the surface, is called a villous adenoma, while tubular adenomas are mainly comprised of tubular glands and have less than 25% villous features. Tubular adenoma (also called adenomatous polyp): Makes up 70 of the polyps found in the colon and can progress into cancer, but this happens over many years. Although a tumor of benign nature, these adenomas are usually considered precancerous and can transform into malignant structures, in contrast to hyperplastic polyps, with no malignant potential.ĭepending on the pattern of growth, these tumors can be villous, tubular, or tubulovillous. Colonic adenomas are raised protrusions of colonic mucosa, i.e., polyps formed by glandular tissue.
