AB There  are  two  major  types  of  lentigines:  lentigo  simplex  and  solar  lentigos.  They  are  benign  lesions.  Although  both  are  clinically  identical,  they  appear  in  entirely  different  clinical  settings.  Lentigo  simplex  typically  first  present  in  childhood  as  multiple  well-demarcated,  brown  or  black  macules  that  can  appear  on  any  part  of  the  skin  or  mucous  membranes.  They  are  clinically  indistinguishable  from  junctional  nevi.  There  is  no  association  with  sun  exposure  in  this  type  of  lentigo.  In  contrast,  solar  lentigos,  more  commonly  known  as  “liver  spots,”  are  well-defined,  brown  macules  that  appear  on  sun-exposed  skin  of  adults.  They  increase  in  number  with  age.  They  most  often  appear  on  the  dorsal  hands,  shoulders,  and  face  of  lightly  pigmented  and  red-haired  patients.
