*

Symptoms  

Acrochordons 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. They don't cause symptoms, even after they appear.

Diagnosis  

Your doctor will ask 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.

Treatment  

Most of the time, no treatment is needed and the acrochordons can be monitored. The acrochordons should be removed if they are bothering you, or if your doctor is concerned about a different skin condition.

Removal options include the following:

  • Surgical removal
  • Electrosurgery
  • Ligation
