Adenoma is a benign tumor of glandular tissue, such as the mucosa of stomach, small intestine, and colon, in which tumor cells form glands or gland like structures.In hollow organs (digestive tract), the adenoma grows into the lumen-adenomatous polyp or polypoid adenoma.ome adenomas grow from epithelial tissue in nonglandular areas but express glandular tissue structure (as can happen in familial polyposis coli).
