AB A  57-year-old  farm  worker  presents  with  itchy  red  rings  on  his  body  that  have  come  and  gone  for  more  than  13  years  (Figures  215-1  and  215-2).  The  erythematous  annular  eruption  was  visible  on  his  abdomen,  legs,  and  arms.  Figure  215-2  shows  the  typical  "trailing  scale"  of  erythema  annulare  centrifugum  (EAC).  A  KOH  preparation  was  negative  for  fungal  elements,  and  the  patient  was  given  the  diagnosis  of  EAC.  He  recently  began  using  paint  thinner  to  "dry  out  the  rash"  and  decrease  the  itching.  Because  topical  steroids  did  not  provide  any  relief  for  him  in  the  past,  we  offered  the  option  of  using  calcipotriol  ointment.  He  chose  to  try  the  calcipotriol  and  stop  using  paint  thinner.
