AB This  is  the  mildest  and  most  common  form  of  ichthyosis,  with  an  incidence  in  school-aged  children  as  high  as  1:250.  It  is  inherited  as  an  autosomal  dominant  trait  and  is  present  in  a  significant  percentage  of  individuals  with  atopic  dermatitis.  It  is  not  present  at  birth.  The  clinical  appearance  of  this  ichthyosis  varies,  depending  on  location.  Figure  12-1  illustrates  the  fine,  bran-like  scaling  on  the  upper  chest.  On  the  anterior  lower  leg,  there  are  often  larger,  plate-like  scales  that  resemble  the  skin  of  a  fish  (Fig.  12-2).  Facial  involvement  is  usually  minimal,  and  flexural  areas  are  typically  spared.  Children  with  ichthyosis  vulgaris  are  likely  to  have  increased  skin  markings  on  the  palms  and  soles  and  a  high  incidence  of  keratosis  pilaris  (see  Figs.  8-46–8-48).  Ichthyosis  vulgaris  tends  to  worsen  in  winter  when  there  is  less  sweating  and  lower  humidity.
