Skin Tag

What happens when a skin tag suddenly turns purple or black?

A thrombosed or clotted skin tag may suddenly change colors, becoming purple, black, and irritated when its blood supply is inadequate. Thrombosed skin tags typically may fall off on their own in three to 10 days and don't require additional treatment.

Skin tags that have changed color or bleed may require your doctor's evaluation and reassurance. Rarely, thrombosed skin tags may be a sign of another condition and need to be biopsied.

Is there another medical name for a skin tag?

Medical terms your physician or dermatologist may use to describe a skin tag include fibroepithelial polyp, acrochordon, cutaneous papilloma, and soft fibroma. All of these terms describe skin tags and are benign (noncancerous), painless skin growths. Some people refer to these as "skin tabs" or warts. However, a skin tag is best known as a skin tag.
