Difference Between Tubular Adenoma and Polyp

Everyone knows that tubular adenomas are fleshy substances like polyps. Polyps are easy to recognize when they grow outside the body, but it is difficult to identify them if they grow inside the body. Because they are almost the same, they just cause different symptoms. Adenomas can grow larger and press on surrounding tissue, while polyps can cause inflammation in the surrounding area. Adenomas can become cancerous, but polyps are less serious. A detailed introduction to the differences between tubular adenomas and polyps is provided for your reference.

Polyps and tubular adenomas are different diseases. Most intestinal polyps are caused by chronic inflammation, while tubular adenomas are a type of tumor in the intestine.

Polyps refer to growths that grow on the surface of human tissue. Modern medicine usually refers to the growths that grow on the surface of human mucosa as polyps, including hyperplastic, inflammatory, hamartomas, adenomas and other tumors. Polyps are a type of benign tumor. The most common clinical manifestations are inflammatory polyps, adenomatous polyps and certain gastrointestinal polyposis syndromes. Although these lesions are benign, some of them have a tendency to become malignant. Cysts that grow under the skin, lipomas in adipose tissue, myomas in muscles, etc. can also cause bulges on the body surface, but they are not classified as polyps.

Tubular adenomas, also known as "adenomatous polyps," are the most common type of colorectal adenoma. The villous component of tubular adenomas accounts for less than 20%. Adenomas are spherical, ellipsoidal or irregular in shape, with a smooth or lobed surface, pink in color, solid in texture, and often have pedicles of varying lengths and thicknesses attached to the intestinal mucosa. However, when the tumor is only a few millimeters in size, it may also be broad-based with no visible pedicle. The larger the tubular adenoma, the greater the chance of malignancy. When the adenoma is >2cm, the rate of canceration increases significantly. If the tumor cells show obvious pleomorphism and interstitial infiltration, it is called severe atypical hyperplasia or carcinoma.
