Dysplastic nevi can be sporadic (much more common) or multiple. In patients with dysplastic nevus syndrome (Familial Atypical Multiple Mole Melanoma syndrome) dysplastic nevi may number in hundreds. Patients with this syndrome are at a great risk of developing melanoma (de novo much more often than complicating a dysplastic nevus) Clinical features •Sporadic>>familial •10% of…
