An accessory nipple is an extra nipple that develops in addition to the usual two nipples. Patients often call this a third nipple, extra nipple or supernumerary nipple. The medical term polythelia is also used for additional nipples without a full accessory breast.
Accessory nipples are usually a benign congenital variation. Some are obvious and look like a small nipple or areola, while others are subtle enough to be mistaken for a mole, birthmark or skin tag. They most often occur somewhere along the embryonic “milk line,” which extends from the armpit toward the groin.
For patients who would prefer to remove an accessory nipple for cosmetic reasons or because it is repeatedly irritated, Dr. Adelyn Ho performs accessory nipple removal under local anaesthetic in her Vancouver office. The goal is to remove the unwanted nipple tissue while planning the resulting scar carefully.
