AB  - The  trunk  is  a  general  term  for  the  core  body  region  including  the  chest,  abdomen,  flanks,  and  back.  The  trunk  has  many  unique  characteristics.  In  many  people  it  is  a  site  of  minimal  sunlight  exposure  as  it  is  usually  covered  by  clothing.  Dermatoses  within  this  distribution  may  be  caused  by  an  allergic  contact  dermatitis  due  to  chemicals  in  clothing,  soaps,  dryer  sheets,  and  other  allergens.  Since  the  trunk  is  generally  covered  by  clothing,  this  occlusion  often  creates  a  warm,  humid  environment  ideal  for  the  development  of  diseases  such  as  folliculitis,  acne,  and  tinea  versicolor.  A  high  density  of  sebaceous  glands  in  the  presternal  area  may  provide  an  ideal  location  for  pityrosporum  ovale  yeast  proliferation,  making  this  a  common  location  for  seborrheic  dermatitis.  Skin  folds,  such  as  the  abdominal  skin  folds  and  inframammary  creases  are  prone  to  intertrigo  and/or  maceration,  increasing  the  risk  of  developing  cutaneous  candida  infections  among  other  dermatoses.  The  trunk  is  the  most  common  location  for  herpes  zoster.  The  umbilicus  is  unique  in  that  it  has  a  high  density  of  apocrine  glands.  Interestingly  some  conditions  including  psoriasis  and  scabies  often  favor  this  site.
