AB A  3-month-old  African  American  boy  is  brought  to  the  clinic  with  white  spots  on  his  face  for  one  month  (Figure  135-1).  The  child  is  otherwise  in  great  health,  eating  well  and  gaining  weight.  The  mother  was  negative  for  HIV  during  pregnancy.  On  physical  exam,  there  are  hypopigmented  patches  on  the  face  especially  at  the  hair  line  and  under  the  eyebrows.  There  is  visible  scale  in  each  of  these  patches.  The  hypopigmentation  occurs  secondary  to  the  toxic  effect  of  the  Malassezia  (Pityrosporum)  on  the  melanocytes  (as  seen  in  tinea  versicolor).  The  diagnosis  of  seborrheic  dermatitis  is  made  and  treatment  is  begun  with  appropriate  topical  agents  to  treat  the  inflammation  and  the  Malassezia.  The  mother  is  told  to  shampoo  the  infant’s  hair  with  a  selenium-based  shampoo  every  1  to  2  days  and  to  apply  1  percent  hydrocortisone  cream  to  the  hypopigmented  areas  twice  daily  for  the  next  2  weeks.  At  a  2-week  follow-up,  the  scale  is  gone  and  the  hypopigmentation  is  resolving.
