an adenoma is a benign tumor of epithelial tissue with glandular origin, glandular characteristics, or both. adenomas can grow from many glandular organs, including the adrenal glands, pituitary gland, thyroid, prostate, and others. some adenomas grow from epithelial tissue in nonglandular areas but express glandular tissue structure (as can happen in familial polyposis coli). although adenomas are benign, over time they may transform to become malignant, at which point they are called adenocarcinomas. most adenomas do not transform. but even while benign, they have the potential to cause serious health complications by compressing other structures (mass effect) and by producing large amounts of hormones in an unregulated, non-feedback-dependent manner (causing paraneoplastic syndromes). some adenomas are too small to be seen macroscopically but can still cause clinical symptoms.

the epithelial tissues are formed by cells that cover the organ surfaces, such as the surface of skin, the airways, the reproductive tract, and the inner lining of the digestive tract. the cells comprising an epithelial layer are linked via semi-permeable, tight junctions; hence, this tissue provides a barrier between the external environment and the organ it covers. in addition to this protective function, epithelial tissue may also be specialized to function in secretion, excretion and absorption. epithelial tissue helps to protect organs from microorganisms, injury, and fluid loss.
