Atypical Mole/Dysplastic Nevus

Description

An atypical mole, also called a dysplastic nevus, is a mole that looks different from a common mole. These moles may be larger than average, have irregular or fuzzy borders, show multiple colors (tan, brown, pink, or dark), and often appear on sun-exposed areas but can develop anywhere on the body.

Most atypical moles are benign (non-cancerous), but they can sometimes resemble melanoma or carry a higher risk of developing into skin cancer. For this reason, people with atypical moles should have regular skin checks and monitor their moles at home for any changes using the ABCDEs of melanoma.

When to come in?

You should schedule a dermatology visit if you notice:

• Changes in size, shape, or color of an existing mole.

• A mole with irregular borders, multiple colors, or asymmetry.

• New moles appearing after age 30.

• A mole that becomes itchy, tender, bleeds, or crusts.

• If you have many atypical moles, a strong family history of melanoma, or have had significant sun exposure or tanning bed use.

Because dysplastic nevi can resemble melanoma under the skin and may carry a higher risk of developing into melanoma, regular skin checks are strongly recommended. Early detection is key in preventing skin cancer.

How are they treated?

Most atypical moles do not need treatment if they appear stable and are not worrisome on exam. Instead, your provider will usually recommend:

• Regular monitoring: Keeping track of the mole during full body skin checks and photographing it for comparison over time.

• Biopsy: If a mole looks suspicious or shows changes (in size, color, border, or shape), a small sample or the entire mole may be removed and checked under the microscope.

• Complete removal: If the biopsy shows abnormal or precancerous cells, the mole may be fully excised (cut out) to prevent progression.

👉 In short: Most atypical moles are simply watched closely, but if they change or look concerning, they are removed for safety.
