AB Acral  surfaces,  such  as  the  feet,  have  unique  characteristics  that  make  them  prone  to  certain  dermatologic  conditions.  The  plantar  surface  of  the  foot  has  the  thickest  keratin  layer,  a  high  concentration  of  eccrine  sweat  glands  as  well  as  sensory  nerves,  Pacinian  corpuscles  and  other  mechanoreceptors.  The  combination  of  abundant  keratin  and  sweat  creates  an  ideal  environment  for  fungal  infections.  Friction  and  contact  with  footwear  also  make  the  feet  susceptible  to  contact  dermatitis.  In  addition,  the  feet  are  disproportionately  affected  by  vascular  disorders,  due  to  their  gravity-dependent  anatomical  location,  and  by  peripheral  small  fiber  sensory  neuropathies.  Since  the  feet  are  a  site  of  frequent  injury,  vascular  disorders  and  sensory  neuropathies  predispose  this  area  to  recurrent  and  difficult  to  manage  wounds.
