Tag, skin: A small tag of skin that may have a stalk (a peduncle). Skin tags may appear on the skin almost anywhere although the favorite locales are the eyelids, neck, armpits (axillae), upper chest, and groin.
Invariably benign, this tiny tumor of the skin usually causes no symptoms unless repeatedly irritated as, for example, by the collar.
Treatment may be done by freezing with liquid nitrogen or by cutting off with a scalpel or scissors if the skin tag is irritating or cosmetically unwanted.
Medically, a skin tag can be termed an acrochordon or a cutaneous papilloma. But it is far better known as a skin tag.
