Can atypical nevi grow?

Atypical moles are very similar to melanoma: both are asymmetrical, multicolored, have an irregular border, and can grow over time.

Is atypical nevus benign?

Atypical moles are benign pigmented lesions. Although they are benign, they exhibit some of the clinical and histologic features of malignant melanoma. They are more common in fair-skinned individuals and in those with high sun exposure.

What is atypical nevus syndrome?

Atypical moles, also known as dysplastic nevi, are unusual-looking moles that have irregular features under the microscope. Though benign, they are worth more of your attention because individuals with atypical moles are at increased risk for melanoma, a dangerous skin cancer.

Should atypical nevi be removed?

Do dysplastic nevi turn cancerous?

No. A dysplastic nevus is more likely than a common mole to become cancer, but most do not become cancer.

Should dysplastic nevus be removed?

Dysplastic nevi can be classified as mild, moderate or severe. Mild is closer to benign, while moderate to severe is closer to melanoma. When diagnosed, most dermatologists will recommend that severe dysplastic nevi be removed as a precaution.

What percentage of dysplastic nevus becomes melanoma?

So even though there is a connection, having a dysplastic nevus doesn’t mean it’s likely to turn into melanoma. In fact, only about 25 percent of melanoma cases start from dysplastic nevi—most melanoma appear on their own, according to a 2020 review in StatPearls Publishing.

How can you tell the difference between atypical moles and melanoma?

Atypical moles are often larger than other nevi (> 6 mm diameter) and primarily round (unlike many melanomas) but with indistinct borders and mild asymmetry. In contrast, melanomas have greater irregularity of color and may have areas that are red, blue, whitish, or depigmented with a scarred appearance.

Are atypical cells cancerous?

On occasion you may see a report from a Pap test or tissue biopsy stating “atypical cells present.” This might cause you to worry that this means cancer, but atypical cells aren’t necessarily cancerous. Many factors can make normal cells appear atypical, including inflammation and infection.

How can you tell the difference between melanoma and dysplastic nevi?

Some dysplastic nevi display more serious warning signs of melanoma: itching, elevation, crusting, oozing, a bluish-black color, pain, bleeding, swelling and ulceration. If any of these warning signs appear on your own skin or that of a friend or family member, consult a dermatologist right away.

How often does dysplastic nevus turn into melanoma?

The authors estimated that the annual transformation rate of any single nevus into melanoma ranged from ≤1 in 200,000 for both men and women younger than 40 years to about 1 in 33,000 for men older than 60 years.

What are the characteristics of an atypical mole?

Although they are benign, they exhibit some of the clinical and histologic features of malignant melanoma. They are more common in fair-skinned individuals and in those with high sun exposure.
