AB Hands  have  structures  with  many  unique  structural  and  functional  features.  As  such,  they  are  prone  to  developing  specific  dermatologic  diseases.  Structurally,  the  palms  have  a  thick  keratin  layer,  a  high  concentration  of  sweat  glands,  Meissner's  corpuscles,  and  other  mechanoreceptors.  Functionally,  we  use  our  hands  to  explore  the  world.  Therefore,  hands  are  subject  to  physical  injury.  Hands  are  often  the  first  body  part  to  come  into  contact  with  objects  and  substances  in  our  environment.  As  a  result,  they  are  frequently  the  site  of  exposure  to  allergens,  irritants,  and  infectious  agents.  This  concept  is  central  to  the  transmission  of  pathogens  and  development  of  certain  dermatologic  conditions  such  as  contact  dermatitis.  Given  their  distal  location,  the  neurovascular  supply  of  hands  (particularly  the  digits)  can  also  predispose  to  neuropathies  and  ischemic  insults.  The  dorsal  hands  tend  to  get  more  sun  exposure  than  centrally  located  anatomical  structures  thereby  subjecting  them  to  photodermatoses  and  actinic  damage.  Hands  may  also  manifest  cutaneous  signs  of  internal  disease.
