AB A  66-year-old  farmer  presents  with  new  growths  on  his  scalp  (Figure  171-1).  The  patient  admits  to  lots  of  sun  exposure  and  has  already  had  one  squamous  cell  carcinoma  (SCC)  excised  from  the  scalp  5  years  ago.  On  close  inspection  there  are  many  suspicious  areas  for  SCC  (Figure  171-1).  Figure  171-2  demonstrates  a  shave  biopsy  of  a  SCC  on  a  scalp  using  a  dermablade.  The  pathology  demonstrated  that  2  of  3  biopsy  sites  were  positive  for  SCC  (E  and  G  were  SCC  and  F  was  read  as  actinic  keratoses).  The  patient  was  referred  for  Mohs  surgery.  The  Mohs  surgeon  recommended  field  treatment  with  5-fluoruracil  for  4  weeks  before  surgery  to  minimize  the  amount  of  cutting  that  would  be  needed  to  clear  the  SCC  from  this  diffusely  sun-damaged  scalp.
