Overview

Dysplatstic nevi are very commonly seen in white people. The prevalence of any atypical nevi in white-skinned populations ranges from 2 to 10 percent. Acquired dysplastic nevi are more common in childhood and adolescence and reach a maximum number in early adulthood.

Epidemiology and Demographics

Incidence

  • The prevalence of any atypical nevi in white-skinned populations ranges from 2 to 10 percent.[1]
  • Some of the prevalence variation is explained by differences in the diagnostic criteria used.
  • In patients with a personal history of melanoma, the estimated prevalence is 30 to 60 percent.  

Age

  • Acquired dysplastic nevi are more common in childhood and adolescence and reach a maximum number in early adulthood.[1]

Race

  • Melanocytic nevi are reported to be less common in Asian and black people.[1]

Gender

  • Males are more commonly affected by dysplastic nevus compared to females.
