AB A  44-year-old  white  man  presents  with  a  painful  nodule  on  his  right  ear  for  1  year  (Figure  29-1).  He  has  a  long  history  of  occupational  sun  exposure  but  no  skin  cancers.  He  states  that  it  is  too  painful  to  sleep  on  his  right  side  because  of  the  ear  nodule.  He  tried  to  remove  it  once  with  nail  clippers  but  it  bled  too  much.  The  patient  is  told  that  this  is  likely  a  benign  condition  called  chondrodermatitis  nodularis  helicis.  A  shave  biopsy/removal  is  performed  for  diagnostic  and  therapeutic  purposes.  It  is  explained  to  the  patient  that  this  could  be  a  skin  cancer  as  a  result  of  his  sun  exposure  history.  The  biopsy  confirms  chondrodermatitis  nodularis  helicis  and  he  is  counseled  to  use  sun  protection.
