Pearls    Atypical  intraepidermal  lymphocytes  with  hyperchromatic  and  hyperconvoluted  nuclear  contours  

 May  have  perinuclear  halos    Pautrier  microabscesses  with  intercalation  of  basal  keratinocytes  with  atypical  lymphocytes  

  Confirm  with  IHC    Confirm  with  clinical  presentation
