Lipomas are slow-growing, nearly always benign, adipose tumors that are most often found in the subcutaneous tissues.1 Most lipomas are asymptomatic, can be diagnosed with clinical examination (Table 1) and do not require treatment.
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). Although adenomas are benign, over time they may transform to become malignant, at which point they are called adenocarcinomas. Most adenomas do not transform.
