AB KEY  POINTSVisual  observation  can  be  more  useful  than  sophisticated  technology  in  distinguishing  abnormalities  from  common  nuances  of  skin  of  color.Futcher  lines,  abrupt  color  demarcations  on  the  flexor  surface  of  the  upper  arm,  are  common  among  adults  with  skin  of  color,  although  rare  in  infants.In  children,  hair  lines,  characterized  by  an  abrupt  linear  demarcation  between  the  darker,  lateral,  lanugo  hair-containing  area  of  the  arm  and  the  medial  non-hairy  area,  occur  in  a  similar  pattern  as  Futcher  lines.Forearm  and  thigh  lines,  less  common  than  Futcher  lines  and  often  hard  to  distinguish,  are  seldom  mentioned  in  the  literature.Linea  nigra  and  linea  alba  demarcations  of  the  trunk  are  common  among  patients  with  darker  skin  of  color.Although  not  found  in  infants,  palmar  and  plantar  hyperpigmentation  becomes  more  common  in  older  patients.Infants  with  darker  skin  of  color  frequently  have  localized  areas  of  hyperpigmentation.Hyperpigmentation  of  the  oral  mucosa  and  sclera,  although  common  in  adults,  is  not  found  in  young  children,  but  infants  often  have  a  lip  discoloration  that  disappears  quickly.Melanonychia  striata,  common  in  older  adults,  is  rare  in  young  children,  suggesting  trauma  as  the  usual  cause,  although  melanoma  must  be  considered.Idiopathic  guttate  hypomelanosis,  characterized  by  hypopigmented  patches  primarily  on  the  anterior  leg,  is  more  common  in  older  patients.Mongolian  spots  that  present  in  Native  American,  Asian,  and  African  American  infants  may  not  appear  in  the  classic  lumbosacral  region  but  rather  on  the  hip.
