Acrochordon

An acrochordon (a.k.a. skin tag, pedunculated papilloma or fibroepithelial polyp) is a small benign tumor that forms primarily in areas where the skin forms creases, such as the neck, armpits and groin. They may also occur on the face, usually on the eyelids. Though larger have been seen, they usually range in size from grain of rice to that of a golf ball. The surface of acrochordons may be smooth or irregular in appearance. Often, they are raised from the surface of the skin on a fleshy stalk called a peduncle. Microscopically, an acrochordon consists of a fibrovascular core, sometimes also with fat cells, covered by an unremarkable epidermis.

Skin tags are harmless, although they are sometimes irritated by clothing or jewelry and can interfere with shaving and other routine grooming. Why and how skin tags form is not entirely known, but there are correlations with age and obesity. They are more common in people with diabetes mellitus and in pregnant women. It is estimated that by age 70, up to 59 percent of people have them.^{[citation needed]} A genetic component (causation) is thought to exist. Rarely, they can be associated with the Birt-Hogg-Dubé syndrome and Polycystic Ovary Syndrome.

Treatment

• Cauterisation: with an electrolysis instrument
• Cryosurgery (freezing)
• Ligation: cutting off blood supply
• Excision: with a scalpel, or other surgical instrument

Each of these treatments are considered minor surgery, typically performed by a physician in the office. In some jurisdictions, however, an aesthetician is permitted to remove them with electrolysis. Since removal of skin tags is considered cosmetic, the procedure is rarely covered by health care systems and medical insurance.
