Skin Tag Other names are an acrochordon, cutaneous papilloma, cutaneous tag, fibroepithelial polyp, fibroma molluscum, fibroma pendulum, soft fibroma, and Templeton skin tags.

Skin tags are very common and generally occur after midlife. They affect men and women equally.

Skin tags are benign, noncancerous, tumors of the skin. They consist of a core of fibers and ducts, nerve cells, fat cells, and a covering or epidermis.

They may appear on the:

  • eyelids
  • armpits
  • under the breasts
  • groin
  • upper chest
  • neck, in the case of papilloma colli

They often go unnoticed, unless they are in a prominent place or are repeatedly rubbed or scratched, for example, by clothing, jewelry, or when shaving.

Some people may have skin tags and never notice them. In some cases, they rub off or fall off painlessly. Very large skin tags may burst under pressure.

The surface of skin tags may be smooth or irregular in appearance. They are often raised from the surface of the skin on fleshy peduncles, or stalks. They are usually flesh-colored or slightly brownish.

Skin tags start small, flattened like a pinhead bump. Some stay small, and some grow bigger. They can range in diameter from 2 millimeters (mm) to 1 centimeter (cm), and some may reach 5cm.
