AB Lichen  sclerosus  (LS)  is  a  benign,  chronic,  inflammatory  condition  of  unclear  etiology  that  results  in  epithelial  atrophy  or  hyperplasia,  and  scarring.  The  condition  typically  occurs  in  the  anogenital  region  (85%-98%),  but  can  develop  on  any  skin  surface.  Female-to-male  ratio  is  10:1  with  onset  often  perimenopausal.  It  occurs  more  frequently  in  women  in  low-estrogen  states  with  autoimmune  conditions  such  as  diabetes  mellitus  type  1,  vitiligo,  and  thyroid  disorders.
