AB A  34-year-old  woman  presents  with  an  itching  rash  on  both  feet  for  the  past  6  months  (Figure  146-1).  She  is  in  otherwise  good  health  and  has  occasionally  tried  some  over-the-counter  (OTC)  athlete's  foot  medicine  for  this  rash  with  slight  improvement.  On  physical  exam,  the  patient  has  erythema  and  scale  in  the  moccasin  distribution  as  well  as  some  of  her  interdigital  spaces.  A  KOH  preparation  is  positive  for  branching  hyphae  with  visible  nuclei  enhanced  by  the  Schwartz  Lamkins  stain  (Figure  146-2).  Patient  denies  a  history  of  hepatitis  or  heavy  alcohol  use  and  would  like  to  try  an  oral  medication  because  she  is  tired  of  the  itching.  The  patient  is  given  oral  terbinafine  250  mg  daily  for  2  weeks.
