Atypical Moles

Atypical moles, also known as dysplastic nevi, are a type of mole that may differ in shape, color, or size compared to common moles. Nevi, the medical term for moles or birthmarks, are clusters of pigment-producing cells called melanocytes, which give the skin its color. While most moles are harmless, atypical moles can sometimes signal a higher risk for skin cancer, including melanoma. Typically, individuals with multiple moles have a greater chance of developing atypical moles. Regular monitoring of these moles is crucial for early detection and prevention of skin cancer.

Causes of Moles

Moles are primarily caused by genetics, sun exposure, immune system conditions, and certain drug treatments. Common moles develop when clusters of melanocytes—pigment-producing cells in the skin—form in one spot. These moles are typically round or oval, flat or raised, and range in color from pink to brown or black, with well-defined borders and a size smaller than a dime. While they are generally harmless, it’s important to monitor them, as some can develop into melanoma over time.

Warning Signs in Moles

Atypical moles, or dysplastic nevi, differ from common moles in both appearance and risk. These moles are often larger, have irregular shapes, poorly defined borders, and a variety of colors. They may also have uneven textures, such as being smooth, flat, or scaly. Atypical moles can appear in sun-exposed areas as well as places that are less exposed to the sun. People with several atypical moles are at a higher risk of developing melanoma, especially if they have a family history of the disease. It is essential to have moles with unusual characteristics evaluated regularly.

When monitoring moles for potential signs of melanoma, the ABCDEs provide a helpful guide to identify atypical moles at higher risk. These key indicators include asymmetry, borders, color, diameter, and evolution. Regular skin exams at home along with annual checks are crucial for early detection and prevention of melanoma. Keep an eye on any new or changing moles and seek professional evaluation as soon as possible.

Treating Atypical Moles

Atypical moles are most often diagnosed through a visual examination using a dermatoscope, a specialized magnifying tool that helps closely examine mole characteristics. During your regular skin check, you will be carefully examined from head to toe, particularly in areas where moles can easily go unnoticed. If any moles appear suspicious, a biopsy may be performed.

Moles with atypical characteristics will be closely monitored over time to watch for any changes. For individuals with a family history of melanoma, more frequent skin checks may be recommended. Depending on the appearance and risk of the mole, dysplastic nevi may either be regularly monitored or biopsied for further evaluation. Atypical moles may be removed as part of regular skin cancer prevention, or for cosmetic reasons. Mole removal is a simple procedure typically performed under local anesthesia. Moles can be removed through excision, shave removal, or laser treatment, depending on the type and location. If necessary, the removed tissue is sent for analysis to check for cancer.
