Do dysplastic nevi change?
Once dysplastic nevi are identified, routine care should include the use of total body photography to track changes of nevi over time. These lesions will change over time(37), but most changes are not worrisome for melanoma. The majority of dysplastic nevi undergo involution over years.
Should dysplastic nevus be removed?
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.

What is compound dysplastic nevus?
- The term "Compound melanocytic nevus" is basically a mole with nevus cells (melanocytes). This is basically a mole. The terms "dysplastic melanocytic nevus" and "there is mild cytologic atypia of melanocytes" basically means that the mole is what is called a atypical mole or dysplastic nevus (they are the same) This is not melanoma.
Can dysplastic nevus grow?
- Dysplastic (Atypical) Nevus. Junctional nevi will typically grow to be 3 or 4 mm across, stop growing sideways, and begin to evolve into a compound nevus. This evolution continues through the compound nevus stage to the dermal nevus stage. In the dermal nevus all of the melanocytes are in the dermis.
