The cause of acrochordons is unknown, however there are several theories. Irritation or friction to the skin, as occurs with skin rubbing on skin in body folds, may play a role in their formation. Acrochordons are found more commonly in people who are overweight or have diabetes. This may be due to body habitus (more skin folds), but some people think insulin resistance may somehow contribute to the development of these harmless tumors. A study of 49 patients with acrochordons showed that the human papilloma virus (HPV) was present in a high percentage of growths, suggesting the virus plays a role in development. It is also possible that acrochordons are genetic or simply due to normal aging and loss of elastic tissue. There is a genetic disorder called Birt-Hogg-Dube Syndrome that is characterized by numerous skin tags along with other skin and systemic findings.
Cutting the skin tag off. Most doctors prefer to remove a skin tag by cutting it off quickly in office. The procedure will begin with cleaning the area with an antiseptic solution. Depending on the size and location of the skin tag, the doctor may rub a numbing solution on your skin. Then, the doctor will use a very sharp tool to simply slice the tag away. The area will be cleaned again and a bandage will be applied. You can expect to feel very little pain during the procedure. Most only feel a pinprick sensation. Occasionally. tag removal may require the doctor to stitch the resulting wound. (5)
