A mole is a skin abnormality that develops when skin grows in a cluster instead of spreading out. These are usually dark, small patches of skin no larger than the size of an eraser head. Although they are most often harmless, some moles can develop into melanoma skin cancer. If you are concerned about a mole that may be cancerous, please refer to our skin cancer treatment page.
Acrochordons can appear as early as the second decade. Typically after age seventy people do not develop new acrochordons. They tend to grow in areas where there are skin folds, such as the underarms, neck, eyelids, and groin. They are skin colored or brown ovoid growths attached to a fleshy stalk. Usually they are small, between 2-5 mm, but can grow to be several centimeters. Acrochordons are not painful but can be bothersome. People frequently complain skin tags get caught on clothing or jewelry.
