An acrochordon (plural acrochorda, and also known as a cutaneous skin tag or fibroepithelial polyp) is a small benign tumour that forms primarily in areas where the skin forms creases, such as the neck, armpit, and groin. They may also occur on the face, usually on the eyelids. Acrochorda are harmless and typically painless, and do not grow or change over time.^[1] Though tags up to a half-inch long have been seen,^[1] they are typically the size of a grain of rice. The surface of an acrochordon may be smooth or irregular in appearance and is often raised from the surface of the skin on a fleshy stalk called a peduncle. Microscopically, an acrochordon consists of a fibro-vascular core, sometimes also with fat cells, covered by an unremarkable epidermis. However, tags may become irritated by shaving, clothing or jewelry. Very large skin tags may burst under pressure.^{[citation needed]}

It is believed that skin tags occur from skin rubbing up against skin, since they are so often found in skin creases and folds.^[1] Studies have shown existence of low-risk HPV 6 and 11 in skin tags hinting at a possible role in its pathogenesis. They are more common in people who are overweight, have diabetes^[1] and in pregnant women.^[2] Acrochorda have been reported to have an incidence of 46% in the general population.^[3] A causal genetic component is thought to exist.^[4] Rarely, they can be associated with the Birt-Hogg-Dubé syndrome and polycystic ovary syndrome.^[5]

Treatment

Because tags are benign, treatment is unnecessary unless the tags become frequently irritated or present a cosmetic concern. If removal is desired or warranted, a dermatologist or similarly trained professional may use cauterization, cryosurgery, surgical ligation or excision to remove the acrochorda.^[1]

There is now an over-the-counter solution that causes skin tag removal. This method freezes the skin tag which results in the skin tag "falling off" in approximately 7–10 days, which is similar to over-the-counter wart removal. ^[6] Some skin tags can also be simply scratched away with minimal pain or bleeding.

A common home remedy involves cutting the skin tag off with sharp, sanitary blade (e.g., scissors or scalpel) just above the area where the skin tag connects to the epidermis. Applying ice or a topical anesthetic beforehand is optional, as there is little to no pain involved if the cut is made swiftly and no incision is made into healthy skin.

Another common home remedy is to knot a piece of thread around the base of a skin tag, which cuts off circulation of blood to the tissue and causes it to fall off. Skin tags treated in this way will usually fall off within 48 hours.^[7]
