Picture of Lipoma 1
A lipoma is a fatty, benign tumor that appears underneath the skin. Lipomas are usually painless, soft, rubbery, and easily movable. They are found most often on the neck, arms, upper thighs, back, shoulders, and arms. Lipomas may occur singularly or in groups. Some lipomas, called angiolipomas, contain large amounts of blood vessels in addition to fat. Most lipomas do not require treatment. If they a lipoma is painful, unsightly, or bothersome, it can be removed surgically.
