Skin tags (or acrochordons) are tiny, noncancerous skin growths. They are benign lesions that are very common in people over the age of 30. They are caused by certain types of HPV (Human Papilloma Virus), but they are different from those that cause the sexually transmitted genital warts.
The areas that are more commonly infected are the neck, face (around the eyes, cheeks), armpits, the fold under the breast and the thigh-inguinal folds.
The skin tags are usually skin-coloured but they may become darker on darker skin types. Their size ranges from very small up to quite large. It should be noted that they may be itchy and painful if they are injured. Often, they may cause trouble to the patient.
They multiply gradually due to friction with clothes and jewelry and that is why they often appear along chains around the neck as well as in areas of friction (under the breast in women). Each individual has specific susceptibility to the virus. They often appear in people of the same family since there is a genetic predisposition to this infection, but also due to transmission through physical contact (hugs, etc.). They are also transmitted through friction and between sexual partners, but the virus does not multiply at the same rate in everyone (e.g. one has too many skin tags that keep growing, while the other has very few ones). They are not affected by the sun. In women, they may increase a lot in number during pregnancy due to the estrogen that favors their growth.
They are treated with laser, diathermocoagulation and cryotherapy. The choice of treatment method depends on the size of the skin tags, their number, the patient’s phototype and the area that may appear.
The treatment is applied at the seasons with no intense sunshine, so that there are no discolorations on the treated areas after sun exposure.
However, the patient should be aware that the tendency to develop skin tags, especially if there are multiple ones, persists even after treatment. So, the patient should have them treated every 2-3 years. There is no drug that prevents relapses.
The treatment procedure is performed after applying a suitable anesthetic cream 1 hour before the treatment to make the procedure painless. After the treatment, instructions are given to use a healing cream for faster healing. Sun protection instructions are given if the skin tags are in sun-exposed areas.
