A skin lesion is an area of the skin that is different than the surrounding skin. This can be a lump, sore, or an area of skin that is not normal. It may also be a skin cancer.
Skin lesion removal is a procedure to remove the lesion.
Most lesion removal procedures are easily done in your doctor's office or an outpatient medical office. You may need to see your primary care provider, a skin doctor (dermatologist), or a surgeon.
Which procedure you have depends on the location, size, and type of lesion. The removed lesion is usually sent to the lab where it is examined under a microscope.
You may receive some type of numbing medicine (anesthetic) before the procedure.
The different types of skin removal techniques are described below.
This technique is used for skin lesions that rise above the skin or are in the upper layer of skin.
Your doctor uses a small blade to remove the outermost layers of skin after the area is made numb. The area removed includes all or part of the lesion.
You usually do not need stitches. At the end of the procedure, medicine is applied to the area to stop any bleeding. Or the area may be treated with cautery to seal blood vessels shut. Neither of these will hurt.
SIMPLE SCISSOR EXCISION
This technique is also used for skin lesions that rise above the skin or are in the upper layer of skin..
Your doctor will grab the skin lesion with a small forceps and lightly pull up. Small, curved scissors will be used to carefully cut around and under the lesion. A curette (an instrument used to clean or scrape skin) maybe used to cut any remaining parts of the lesion.
You will rarely need stitches. At the end of the procedure, medicine is applied to the area to stop any bleeding. Or the area may be treated with cautery to seal blood vessels shut.
SKIN EXCISION - FULL THICKNESS
This technique involves removing a skin lesion in the deeper levels of the skin down to the fatty layer under the skin. A small amount of normal tissue surrounding the lesion may be removed to ensure it is clear of any possible cancer cells (clear margins). It is more likely to be done when there is a concern about a skin cancer.
The area is closed with stitches. If a large area is removed, a skin graft or flap of normal skin may be used to replace the skin that was removed.
CURETTAGE AND ELECTRODESICCATION
This procedure involves scraping or scooping out a skin lesion. A technique that uses high frequency electrical current may be used before or after. This is called electrodesiccation.
It may be used for superficial lesions that do not need a full thickness excision.
A laser is a light beam that can be focused on a very small area and can treat very specific types of cells. The laser heats the cells in the area being treated until they "burst." There are several types of lasers. Each laser has specific uses.
Laser excision can remove:
Cryotherapy is a method of super-freezing tissue in order to destroy it. It is most commonly used to destroy or remove warts, actinic keratoses, seborrheic keratoses, and molluscum contagiosum.
Cryotherapy is done using a cotton swab that has been dipped into liquid nitrogen or a probe that has liquid nitrogen flowing through it. The procedure usually takes less than a minute.
The freezing may cause some discomfort. Your doctor may apply a numbing medicine to the area first. After the procedure, the treated area may blister and the destroyed lesion will peel away.
Mohs surgery is a way to treat and cure certain skin cancers. Surgeons trained in the Mohs procedure can do this surgery. It is a skin-sparing technique that allows skin cancer to be removed with less damage to the healthy skin around it.
It may be done to improve a person's appearance, or if the lesion is causing irritation or discomfort.
Your doctor may recommend having a lesion removed if you have:
Risks of a skin excision may include:
Tell your doctor:
Follow your doctor's instructions on how to prepare for the procedure.
.The area may be tender for a few days afterward.
Taking proper care of your wound will help your skin look its best. Your provider will talk with you about your options:
Having lesions removed works well for many people. Some skin lesions, such as warts, may need to be treated more than once.
