Is dysplastic nevus melanoma?

A dysplastic nevus may develop into melanoma (a type of skin cancer), and the more dysplastic nevi a person has, the higher the risk of melanoma. A dysplastic nevus is sometimes called an atypical mole.

Is dysplastic nevi skin cancer?

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

Can dysplastic nevi be removed?

Surgical excision of the lesion with a 2- to 3-mm margin of normal skin followed by closure of the skin is the standard method for removal of a biopsy-diagnosed dysplastic nevus.

Is a dysplastic nevus precancerous?

An atypical mole, also sometimes called a dysplastic nevus, is a benign but unusual-looking mole that can look a lot like a melanoma. It’s important to be aware of these moles, because they can turn into melanomas.

Should I be worried about dysplastic nevus?

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.

Can a nevus turn into melanoma?

Yes — but most dysplastic nevi do not turn into melanoma. Most types of atypical moles remain stable over time. Patients with five or more dysplastic nevi are 10 times more likely to develop melanoma than individuals with no atypical moles.

How serious is dysplastic nevus?

Those diagnosed with dysplastic nevi have an excellent prognosis. However, if you have a history of dysplastic nevi you have a greater risk of developing melanoma in the future.

When should dysplastic nevus be removed?

Most dermatologists usually recommend that all patients with these severely dysplastic moles have them removed with a margin (0.5 cm-about a quarter inch) of clinically normal skin. Also many dermatologists recommend removing “moderate dysplasia” moles, if the biopsy didn’t get all of it.

What percentage of dysplastic nevus becomes melanoma?

Most studies have found that approximately 20% of melanomas arise out of a DN; the numbers arising out of other types of nevi have not been well quantified and the majority of melanoma tumors arise de novo(7). Although DN may be designated as precursors, the dysplastic nevus itself rarely progresses to melanoma.

What causes dysplastic nevus?

What causes dysplastic nevi? Genetics and sun exposure combine to play a role in the development of dysplastic nevi. Sometimes they can develop on parts of the skin that received little or no sun exposure.

Can a dysplastic nevus grow back?

Melanocytic nevi, including dysplastic or atypical nevi (DN), can recur or persist following shave removal procedures, and recurrence may resemble melanoma, both clinically and histologically (pseudomelanoma).

How can you tell the difference between melanoma and nevus?

Early melanomas may be differentiated from benign nevi by the ABCDs, as follows:

1. A – Asymmetry.
2. B – Border irregularity.
3. C – Color that tends to be very dark black or blue and variable.
4. D – Diameter ≥6 mm.
