Definition
Acrochordons are harmless skin growths that appear to hang off the skin. Acrochordons can be mistaken for a more serious condition, so if you think you have one, see your healthcare provider.
Causes
Acrochordons consist of collagen fibers and blood vessels that are surrounded by a thin layer of skin. It is not clear what causes them.
Risk Factors
A risk factor is something that increases your chance of getting a disease or condition. The following factors increase your chance of developing acrochordons. If you have any of these risk factors, tell your doctor:
- Skin chafing and irritation
- Pregnancy
- Acromegaly (gigantism)
- Insulin resistance
- Human papilloma virus
- Obesity
- Type 2 diabetes
- Crohn's disease
Symptoms
Acrochordons are usually flesh-colored, but may be darker in color. They are generally small, but can range in size from 1 millimeter to 5 centimeters in diameter. They are often found in folds of the skin.
Diagnosis
Your doctor will ask about your symptoms and medical history, and perform a physical exam. Most acrochordons can be diagnosed without invasive tests. In some cases, a skin biopsy may be necessary.
Treatment
Talk with your doctor about the best treatment plan for you. Acrochordons need to be differentiated from neurofibromas, as well as other benign skin lesions. Treatment options include the following:
Cryotherapy
Cryotherapy involves freezing the acrochordon so it falls off.
Surgical Excision
Acrochordons can be removed surgically with scissors.
Electrosurgery
In electrosurgery, an electric current is applied to the acrochordon to cut it off.
Ligation
With ligation, a suture is tied around the neck of the acrochordon to remove it.
