AB Melanocytic  lesions  are  extremely  common  in  pediatric  patients.  At  least  1  melanocytic  nevus  develops  by  early  childhood  in  more  than  95%  of  fair-skinned  individuals.1  Dermal  melanocytosis  and  other  pigmented  lesions  such  as  freckles,  lentigines,  café  au  lait  macules,  and  Becker  nevi  are  also  frequently  observed  in  children  and  adolescents.  In  addition,  a  variety  of  disorders  characterized  by  increased  or  decreased  cutaneous  pigmentation  can  present  in  childhood,  ranging  from  postinflammatory  hyperpigmentation  and  hypopigmentation  to  vitiligo  to  patterned  pigmentation  reflecting  cutaneous  mosaicism.  Genetic  diseases  with  pigmentary  manifestations  (eg,  oculocutaneous  albinism,  piebaldism,  Waardenburg  syndrome,  tuberous  sclerosis,  neurofibromatosis)  are  reviewed  in  Chapter  360.  It  is  important  for  pediatricians  to  be  aware  of  the  clinical  spectrum  and  natural  history  of  benign  melanocytic  lesions  and  self-limited  disorders  of  pigmentation  in  children  as  well  as  of  findings  that  should  raise  concern.
