What is Dysplastic Nevi?
Dysplastic Nevi are atypical moles that exist on the spectrum between benign and malignant. These moles may be larger than normal, often bigger than a pencil eraser, and appear irregularly shaped. They tend to have uneven color with dark, brown edges and lighter, abnormal borders.
However, though dysplastic nevi have unusual features and growth patterns, they usually are not cancerous (but some may have a higher chance of turning into a melanoma or indicate that a person may have a higher risk of developing a melanoma later in life).
Mole & Dysplastic Nevi FAQs
Though scientists and researchers haven’t discovered all of the events responsible for creating atypical moles, it’s believed there are two main drivers behind the development of dysplastic nevi: genetics and environmental factors, such as sun exposure.
Dysplastic nevi can usually be diagnosed with a thorough skin evaluation by a board-certified dermatologist. However, when checking out your skin at home, you can follow the ABCDE guideline developed by the American Academy of Dermatology:
- A for Asymmetrical: Do the two halves of a mole match up?
- B for Borders: Does the mole have an irregular perimeter?
- C for Color: Does the mole feature multiple colors or different shades of brown/black?
- D for Diameter and Dark: Is the mole larger than a pencil eraser, and is it darker than others?
- E for Evolving: Have you noticed a change in size, shape, color, or elevation of a spot?
Dysplastic nevi are not skin cancers but they may be referred to as “precanceous” given the possibility that a future melanoma may develop (within the mole itself or elsewhere on the body). Many remain stable over time and do not become melanoma. However, research suggests the chance of melanoma is about 12x greater for someone with more than 10 dysplastic nevi than for someone who has none. And the more dysplastic nevi a person has, the greater the chance of developing melanoma.
In many cases, dysplastic nevi do not require treatment. However, if you have multiple atypical moles, your board-certified dermatologist will likely want to monitor them for any changes. Additionally, if your dermatologist thinks a mole looks suspicious, you might need a biopsy for a definitive diagnosis.
Not all atypical moles need to be removed, as the likelihood of them turning into melanomas is low. However, dermatologists might remove dysplastic nevi that are severely atypical or an atypical mole that has changed shape, color, or size.
