tubulovillous adenoma

[tube-yoo-lo-VIH-lus ad-no-muh or ad-uh-NO-muh] a type of benign (not cancer) polyp in the colon or other parts of the digestive tract that is made up of gland cells formed into tubes, along with finger-like projections of gland cells when seen under a microscope. In these, the finger-like parts usually make up 25% to 50% of the adenoma. These adenomas can be pre-cancerous, and are generally removed when found. See also adenomatous polyp, polyp, tubular adenoma, villous adenoma.
