Skin tags are small portions of the skin that appear to be attached to or protrude from normal skin and are a common benign condition of the skin.
Usually just a few millimeters in diameter, skin tags vary in appearance. Some are the same color as surrounding skin while others are hyperpigmented. In most cases, they are attached to the underlying skin by a small band of tissue called a stalk or peduncle.
Skin tags can occur almost anywhere there is skin. Areas for tags are the eyelids, neck, armpits, upper chest (particularly under the female breasts), and groin folds.
Tags are typically thought to occur in characteristic locations where skin rubs against skin or clothing.
