Acrochordons are harmless skin growths that appear to hang off the skin. They are more commonly known as skin tags.

Skin tags consist of collagen fibers and blood vessels that are surrounded by a thin layer of skin. It is not clear what causes them.
Factors that increase your risk of getting skin tags include:
Skin tags usually appear as flesh-colored skin growths. 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, typically in arm pit, neck, or groin. They don't cause symptoms, even after they appear.
You will be asked about your symptoms and medical history. A physical exam will be done. Most acrochordons can be diagnosed without invasive tests. In some cases, a skin biopsy may be necessary to rule out other skin conditions.
Most of the time, no treatment is needed and the skin tags can be monitored. The skin tags should be removed if they are bothering you, or if your doctor is concerned about a different skin condition.
