Acrochordon, also known as skin tag is an overgrowth of the skin hanging loose from the surrounding area and is connected by a stalk (peduncle). Acrochordons are normally benign growths; they are soft wrinkled protrusions and appear in flesh or light brown color. They are filled with collagen fibres and blood vessels with a thin layer of skin covering them.
They do not cause any pain and small growths may just fall off unknowingly. Slightly bigger acrochordons do not fall on their own and need to be removed using various methods. Though they can occur anywhere on the body, the areas like under arms, eyelids, upper chest, neck, and groin are more prone to develop skin tags as the skin here rubs against the clothing or with the adjoining skin. Acrochordon occurs in both men and women and the frequency of the condition increases as we age.
What causes Acrochordon?
Skin tags are caused by the constant rubbing between the skins of adjacent sites. Obesity is one of the very obvious causes that lead to acrochordon. These people tend to develop more skin tags simply because they have more skin folds on their body. Research also shows that this condition is inherited: people with close relatives having acrochordons have higher chances of developing this skin condition. Pregnant women also have a tendency to develop skin tags due to the hormonal changes taking place in their bodies. Diabetic patients are also prone to skin tags. Wart virus or human papilloma virus also cause skin tags.
Clinical examination is sufficient to diagnose the acrochordon. Yet in case of suspicion, doctor may advise skin biopsy. This procedure involves removal of small piece of skin to be examined in laboratory. This is done to rule out any malignancy of the growth.
Treatment of Acrochordon
Typically acrochordons do not require any treatment and they need not be removed. But the bearer may choose to get it removed either for cosmetic reasons or if the tags become bothersome. A word of caution here, if the skin tags are changing color or growing too quickly it is advisable to show it to your physician to rule out any further complications. Cryosurgery is used extensively, where the skin tag is removed by freezing it using the liquid nitrogen. Cauterization is one more method which involves burning of the skin tag using electrolysis (heat). Skin tags are also removed by surgical excision.
