Skin Tag: Symptoms & Signs

Medically Reviewed on 10/22/2020

A skin tag, medically known as an acrochordon, is a small, flesh-colored benign growth on the skin. The growth is often attached to the underlying skin by a stalk. Skin tags occur in almost everyone and are seen most often on the eyelids, neck, armpits, groin folds, and under the breasts.

Signs and symptoms include a small growth of normal skin or darkening of the skin that may bleed when irritated. Most are very small and have a diameter of 2-5 mm, but in certain conditions, they may grow larger.

Cause of skin tags

The exact cause of skin tags is unknown. Obesity seems to be a risk factor for the development of skin tags, but they are also found in non-obese people.
