Lipoma swelling. Shoulder of a 9-year- old boy with a lipoma. This is a benign tumour composed of fatty tissue. It is a painless, harmless soft swelling that is usually removed for cosmetic reasons. However, multiple swellings may be an indication of Dercum's disease, a rare condition that results in many painful fatty deposits under the skin.
