AB Hypertrophic  scars  and  keloids  are  both  characterized  by  excess  fibrous  tissue  at  a  site  of  injury  in  the  skin.  Hypertrophic  scars  are  confined  to  the  original  wound  site,  whereas  keloids,  by  contrast,  extend  beyond  the  original  wound  site  (Table  61.1).  Both  are  common  and  frequently  disturb  patients  greatly,  both  as  an  unsightly  scar  as  well  as  a  reminder  of  previous  trauma  or  surgery.  Acne  scars  result  from  the  loss  of  underlying  collagen  and  elastic  tissue  from  dermal  inflammation  associated  with  acne,  particularly  cystic  acne.  Acne  scars  are  also  very  common  and  a  source  of  distress  to  the  patient,  both  for  their  obvious  appearance  on  the  face  as  well  as  a  reminder  of  previous  acne.
