AB This  chapter  discusses  melanocytic  nevi,  defined  as  benign  neoplasms  of  melanocytes,  most  of  which  manifest  themselves  as  cutaneous  pigmented  lesions.  They  are  characterized  by  the  presence  of  banal  melanocytic  cells  in  nests  (defined  as  three  or  more  melanocytes  in  direct  contact  [also  known  as  thèque]),  within  the  epidermis,  dermis,  or  in  other  tissues.  The  melanocytic  cells  forming  these  nevi  are  referred  to  as  nevomelanocytes.  The  term  melanocytic  hyperplasia  is  a  descriptive  term  used  to  indicate  increased  melanocytes  confined  to  the  basal  layer  of  the  epidermis  in  the  absence  of  nest  formation.
