Should you remove dysplastic nevus?

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.

Is dysplastic nevus cancerous?

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

Is dysplastic nevus benign or malignant?

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.

How often does dysplastic nevus turn into melanoma?

These goals include melanoma detection and prevention. The lifetime transformation risk of an “average” dysplastic nevus into melanoma is estimated at 1 in 10 000, though risk likely varies with grade of atypia.

Is a severely dysplastic nevus melanoma?

A severely dysplastic nevus is indistinguishable from early melanoma. Very often these lesions show considerable irregularity of edge and irregularly irregular colour. The differentiation between a moderate and severely dysplastic nevus is one of degree.

What is the difference between dysplastic nevus and melanoma?

Dysplastic nevi, also known as atypical moles, are unusual benign moles that may resemble melanoma. People who have them are at an increased risk of melanoma. The larger the number of atypical moles, the greater the risk.

Can dysplastic nevi appear suddenly?

Moles, or nevi, typically form during childhood and adolescence, but new moles can appear in adulthood. Although most moles are noncancerous, or benign, the development of a new mole or sudden changes to existing moles in an adult can be a sign of melanoma.

Can dysplastic nevus come 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 melanoma from 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.

Can a dysplastic nevus grow?

Dysplastic nevi do not age properly. The junctional phase can be prolonged, so that the lesion grows beyond 6 mm. Very often, with increasing size, the lesion shows increasing variation in colour and edge.

When do dysplastic nevi appear?

Dysplastic moles usually appear in individuals during their 20s and can be found anywhere on the body, such as the scalp, but are more common on sun-exposed areas, such as the trunk and extremities. Dysplastic moles have a higher tendency to develop into malignant melanoma than benign moles.

What should be the management of a dysplastic nevi?

Management of a biopsy-proven dysplastic (atypical) nevus with a positive histologic margin remains ill defined. Particularly after a biopsy finding of mildly or moderately dysplastic nevus with positive histologic margin, there is significant variation and lack of consensus in subsequent management.

What kind of mole is a dysplastic nevi?

Dysplastic nevi are diagnosed after a biopsy is done on a suspicious mole. My doctor told me I have a moderately dysplastic nevus. What does this mean? Dysplastic nevi are categorized as mild, moderate, or severe. Remember, a dysplastic nevus is a mole that exists in the spectrum between a benign mole and melanoma.

What is the grade of dysplastic nevus on a biopsy?

Grade of dysplastic nevus and association with biopsy margin positivity, frequency of excision after positive biopsy margin, frequency of residual nevus in excision specimen, and clinically significant change in diagnosis upon excision. Figure 2.

Can a dermatologist diagnose melanoma in dysplastic nevi?

•“…if melanoma risk is related to degree of cytologic atypia in dysplastic nevi, dermatopathologists must be able to reliably distinguish two or more grades of melanocytic atypia in dysplastic nevi.” Duncan, L et al. J Invest Dermatol; 100: 318S
