Types of Melanocytic Nevi

Melanocytic nevi are classified into different types based on their appearance and location. Common types include junctional, compound, and intradermal nevi, with junctional nevi being flat and compound nevi having both flat and raised areas. Intradermal nevi are typically skin-colored and may appear as small bumps.

Causes and Risk Factors

The development of nevi is influenced by genetic factors, sun exposure, and skin type. People with lighter skin tones or those exposed to the sun frequently are more likely to develop moles. Additionally, family history can play a role in the number and type of moles one may have.
Melanocytic nevi are benign skin growths, commonly known as moles, that appear on the skin after birth. They can vary in appearance and are influenced by genetic factors, sun exposure, and skin type.

When to Worry: Signs of Atypical Nevi

Atypical nevi, or dysplastic nevi, differ from regular moles in size, color, and shape. They may be larger than 5 mm, have irregular borders, and contain multiple colors. These features can increase the risk of melanoma, so monitoring changes in moles is crucial.

FAQs

What are melanocytic nevi?

They are benign skin growths, commonly known as moles.

Are all moles a cause for concern?

No, but atypical nevi may warrant closer observation.

Can sun exposure affect mole development?

Yes, sun exposure can increase the number and size of moles.
