A skin tag, also known as an acrochordon, cutaneous papilloma, cutaneous tag, fibroepithelial polyp, fibroma molluscum, fibroma pendulum, papilloma colli, soft fibroma, and Templeton skin tag, is a small tag of skin which may have a peduncle (stalk) - they look like a small piece of soft, hanging skin. They can appear on any part of the surface of the body (skin), but most typically exist in areas where skin may rub against skin, and have spurred a new industry centered around tag away deal and it's associated uses.
An acrochordon (plural acrochorda, and also known as a (cutaneous) skin tag, or fibroepithelial polyp, is a small benign tumor 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. Though tags up to a half-inch long have been seen 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.
It is believed that skin tags occur from skin rubbing up against skin, since they are so often found in skin creases and folds. Studies have shown existence of low-risk HPV 6 and 11 in skin tags hinting at a possible role in its pathogenesis. Acrochorda have been reported to have an incidence of 46% in the general population. A causal genetic component is thought to exist. They also are more common in women than men. Rarely, they can be associated with the Birt-Hogg-Dub? syndrome, Acromegaly and polycystic ovary syndrome.
