AB KEY  POINTSLichen  planus  is  an  autoimmune  inflammatory  mucocutaneous  condition  affecting  the  skin,  mucosal  surfaces,  scalp,  or  nails.Evidence  suggests  that  lichen  planus  is  due  to  altered  self-antigens  on  basal  keratinocytes,  a  process  that  appears  to  be  multifactorial.Lichen  planus  has  a  multitude  of  clinical  variants,  including  some  actinic  variants  that  occur  in  darker  skin  types.Lichen  nitidus  is  characterized  by  clusters  of  numerous,  tiny,  discrete,  skin-colored,  uniform,  pinhead-sized  papules.Histology  of  lichen  nitidus  reveals  a  ‘ball  and  claw’  arrangement.There  is  an  actinic  variant  of  lichen  nitidus  that  occurs  predominantly  in  people  with  more  darkly  pigmented  skin.
