Skin Tag Orgins and Removal Treatments

What are skin tags?

Skin tags are small, benign growths that are composed of a core of fibers and ducts, nerve cells, fat cells, and a covering or epidermis. Additional names for skin tags include acrochordon, cutaneous papilloma, cutaneous tag, fibroepithelial polyp, fibroma molluscum, fibroma pendulum, papilloma colli, soft fibroma, and Templeton skin tag. They are often seen raised from the skin on a stalk called a peduncle.

Who gets skin tags?
Both men and women tend to get skin tags as they age. Skin tags are also more common in pregnant women, obese people, and people with type 2 diabetes mellitus. About 46% of people develop skin tags at some point in their lives.

Where do skin tags appear?
Skin tags often form in areas where the skin creases, such as the neckline, the groin, the underside of the arms, the area beneath the breasts, and the eyelids. The most common location is the armpit. It is common for skin tags to appear in groups. They often become stuck on jewelry, are shaved in error, and are agitated by clothing. Women who shave their armpits should be careful not to shave or cut skin tags that are located there.

Are skin tags harmful?
Although skin tags are technically tumors, they are benign and normally harmless. They can, however, become damaged and become inflamed and sore. If shaved off or rubbed hard, they may bleed.

What causes skin tags?
Although we do not know the exact cause of skin tags, the following are thought to be associated with their appearance:

* Chaffing and irritation from the skin rubbing together
* Hormones secreted during pregnancy or in cases of acromegaly (gigantism)
* Insulin resistance caused by diabetes
* Human papilloma virus
* Illegal steroid use that interferes with the body and muscles, causing the collagen fibers in the skin to bond so that skin tags are formed

How are skin tags removed?
Since skin tags are generally harmless, they are usually removed for aesthetic or cosmetic reasons. Physicians usually remove skin tags using one of the following methods:

* Cauterizatio - the skin tag is burned off using electrolysis
* Cryosurgery - the skin tag is frozen off using liquid nitrogen
* Ligation - the blood supply to the skin tag is interrupted
* Excision - the skin tag is removed with a scalpel

Skin Tags and Seborrheic Keratoses

Nuisances You don’t have to put up with. As time goes on, we all acquire tiny bits of extra skin called skin tags. These can range in size from 1-10 mm, and are flesh colored or brown.

Skin tags can be found on any part of the body, but are most common on the eyelids and neck, and in the armpits and groin, and under the breasts.  While skin tags are benign they can be annoying if they become irritating or rub on sporting equipment, and skin tags can interfere with shaving and can detract from one’s appearance and self-image.

Fortunately, we don’t have to put up with skin tags. These little annoyances can be easily removed in an office visit with little or no discomfort. Skin tags can almost always be removed without needing stitches, and the treated areas usually have healed completely in a week or two.

The cost of removing skin tags is quite reasonable - ranging from about $80 for a few tiny ones to about $200 for a larger number scattered over several areas.

Seborrheic keratoses are firm flat or raised, sometimes scaly or crusty flesh-colored, brown or black “barnacles” which accumulate (usually on the face and trunk) as time goes on. Some people start to develop seborrheic keratoses in their thirties, and most people have at least a few by the time they are sixty.

Seborrheic keratoses are usually just a nuisance, but - like skin tags — they can rub on clothing and equipment, and their appearance can sometimes be so distressing that they interfere with choice of clothing, sports like swimming, and intimacy.  Because seborrheic keratoses grow above the skin (but not down into the skin) they can be easily scraped off, and the treated areas heal up nicely within a few weeks. Sometimes the healed area remains pink for a few months after the seborrheic keratosis is removed.

The cost of removing seborrheic keratoses is similar to that for removal of skin tags: about $80 for one or two, with the cost gradually increasing depending on the number and size of seborrheic keratoses to be removed.

The cost of removing skin tags and seborrheic keratoses is a tax-deductible medical expense, just like things like dental bills.  So, if you are annoyed by skin tags or seborrheic keratoses you can be confident that it is simple and inexpensive to rid yourself of these nuisances.
