Atypical moles, also called dysplastic moles, are very common. An estimated one out of every 10 Americans has at least one atypical mole. These moles are larger than common moles, with borders that are irregular and poorly defined.
Are atypical moles always cancerous?
Less common are atypical moles (dysplastic nevi). These moles aren’t cancerous, but they can turn into cancer. About 1 out of every 10 Americans has at least one atypical mole. The more of these moles you have, the greater your risk of developing melanoma — the deadliest type of skin cancer.
Are atypical moles dangerous?
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 an atypical mole be 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.
Does an atypical mole need to be removed?
The greatest risk of melanoma is in patients who have more than 50 atypical moles and two or more family members with melanoma (familial atypical mole and melanoma syndrome). Atypical moles should be removed when they have features suggestive of malignant transformation.
How can you tell the difference between atypical moles and melanoma?
Like dysplastic nevi, melanoma presents itself as an asymmetrical, multicolored growth with an irregular border.
Some other characteristics of atypical moles are:
- Larger than average moles.
- The surface can be bumpy or smooth.
- Can have a raised darker center surrounded by a flat, lighter area.

What is atypical mole syndrome?
Atypical mole syndrome (AMS), also known as dysplastic nevi syndrome (DNS), B-K mole syndrome, Clark nevi syndrome, or familial atypical multiple mole melanoma (FAMMM) syndrome, is a condition characterized by a large number of pigmented nevi with architectural disorder, which arise sporadically or by inheritance and …
Do atypical moles grow back?
Remember, most individuals with a history of multiple dysplastic moles are more likely to develop malignant melanoma. Your dermatologist will inspect your skin for any new moles and will ensure that any previously treated moles are not growing back.
How long does melanoma take to kill?
Melanoma can grow very quickly. It can become life-threatening in as little as six weeks and, if untreated, it can spread to other parts of the body. Melanoma can appear on skin not normally exposed to the sun. Nodular melanoma is a highly dangerous form of melanoma that looks different from common melanomas.
Do atypical moles change over time?
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. The greater the number of dysplastic nevi on the body, the more likely the development of melanoma.
What percent of atypical moles become melanoma?
Atypical moles and melanoma risk
One study found that the risk of an atypical mole turning into melanoma over an individual’s lifetime is less than 0.1% for both men and women.
What percentage of biopsied moles are melanoma?
Lab testing showed that more than 90 percent of biopsied moles were completely removed by using the single procedure, with 11 (7 percent) diagnosed as melanoma, one of the most aggressive forms of skin cancer.
Can benign moles have irregular borders?
Atypical moles are benign melanocytic nevi with irregular and ill-defined borders, variegated colors usually of brown and tan tones, and macular or papular components. Patients with atypical moles have an increased risk of melanoma.
How do you get rid of atypical moles?
Atypical Mole Removal Procedures
The first step to treat melanoma is to remove the mole (or an area of the mole) and examine the skin cells. During a shave biopsy procedure, a thin layer of skin in the affected area is removed with a small blade (similar to a razor).
Will mole grow back after removal?
If a common mole is removed completely, it should not grow back. However, some Conroe residents may experience the regrowth of a mole if some of the mole cells were left behind after the mole removal procedure. But a mole that grows back does not mean it is cancerous. To avoid regrowth, be sure to talk to Dr.
