Atypical and Dysplastic Nevi | Odd Moles
Atypical and dysplastic nevi are moles that look different from typical benign moles. These moles are generally larger, have irregular borders, and may exhibit a range of colors. While most atypical and dysplastic nevi are benign, they can resemble melanoma, the most dangerous type of skin cancer, and may have a higher risk of developing into melanoma over time. Therefore, it’s crucial to monitor these moles closely and consult with a dermatologist if you notice any changes.
Characteristics of Atypical and Dysplastic Nevi
Atypical and dysplastic nevi can vary widely in appearance, but they often share the following features:
Size: These moles are usually larger than 6mm in diameter, about the size of a pencil eraser.
Shape: They often have irregular, asymmetrical shapes where one half of the mole does not match the other.
Borders: The edges are often ragged, blurred, or uneven.
Color: Atypical nevi may contain multiple shades of brown, tan, pink, or even black within the same mole.
Surface: The texture may be smooth, rough, or raised, and some moles might feel different from the surrounding skin.
Risk Factors for Atypical and Dysplastic Nevi
While atypical nevi can occur in anyone, certain factors may increase the likelihood of developing these moles:
Genetics: A family history of atypical nevi or melanoma increases the risk of developing atypical moles.
Sun Exposure: Prolonged or intense exposure to ultraviolet (UV) radiation from the sun or tanning beds can contribute to the development of atypical nevi.
Skin Type: Fair-skinned individuals who burn easily are more prone to developing both atypical moles and melanoma.
Monitoring and When to Seek Evaluation
Because atypical and dysplastic nevi can resemble melanoma, it is essential to monitor these moles for any changes. Dermatologists recommend regular self-examinations and professional skin checks, particularly if you have a large number of moles, a family history of skin cancer, or if you notice any of the following changes:
Asymmetry: One half of the mole does not match the other.
Border Irregularity: The edges become uneven, scalloped, or poorly defined.
Color Changes: The mole shows varying colors or becomes darker.
Diameter: The mole grows larger than 6mm.
Evolving: Any change in size, shape, color, or symptoms (such as itching or bleeding).
If any of these changes are observed, it’s crucial to have the mole evaluated by a dermatologist. In some cases, a biopsy may be performed to rule out melanoma.
Treatment Options
Treatment for atypical and dysplastic nevi typically depends on the mole’s appearance and any associated risks. Options include:
Observation: Regular monitoring through skin checks, both self-examinations and professional evaluations, may be recommended for moles that are not immediately concerning.
Biopsy: If a mole is suspicious, a dermatologist may perform a biopsy to determine whether the mole is benign or cancerous.
Excision: If a mole is deemed at risk of developing into melanoma, or if it causes cosmetic concerns, it may be surgically removed.
