Moles are pigmented skin growths, also called nevi, that can appear anywhere on the body singly or in groups. Almost all adults have at least a few and some may have up to 40. Normally appearing as a dark brown spot, a mole may also be blue, black, pink or flesh-colored or may be raised and highly visible. Some may change over time or even gradually disappear. Whatever their color or shape, most moles are harmless and cause no symptoms other than discomfort when they rub against something.
Skin tags are extremely common small tissue growths on the skin’s surface.  Up to half of all people may get one at more at some point in their lifetime. Most often, skin tags are harmless, painless, and don’t grow or change. While you can find them all over your body, skin tags often form on areas of the body subject to rubbing. You are most likely to find them on the neck, armpits, trunk and in body folds. (1)
The cause of acrochordons is unknown, however there are several theories. Irritation or friction to the skin, as occurs with skin rubbing on skin in body folds, may play a role in their formation. Acrochordons are found more commonly in people who are overweight or have diabetes. This may be due to body habitus (more skin folds), but some people think insulin resistance may somehow contribute to the development of these harmless tumors. A study of 49 patients with acrochordons showed that the human papilloma virus (HPV) was present in a high percentage of growths, suggesting the virus plays a role in development. It is also possible that acrochordons are genetic or simply due to normal aging and loss of elastic tissue. There is a genetic disorder called Birt-Hogg-Dube Syndrome that is characterized by numerous skin tags along with other skin and systemic findings.

The location and size of a mole may cause cosmetic concerns, as well as physical irritation. For instance, if a mole exists on a certain part of the neck, it may become caught in a necklace, causing discomfort and sometimes bleeding. We think these are good reasons to seek cosmetic mole removal, and we are happy to help you feel more comfortable and more satisfied with your appearance. More than just removing moles for cosmetic reasons, our team ensures that we evaluate all moles before removal to rule out abnormalities that may indicate skin cancer.
