AB  - A  skin  lesion  that  is  suspicious  for  melanoma  is  best  removed  by  excisional  biopsy  with  a  1-  to  2-mm  clinical  lateral  margin  and  a  deep  margin  into  the  subcutaneous  fat,  underneath  all  epithelial  appendageal  structures.1  This  can  be  performed  on  most  lesions  up  to  1.5  cm  in  diameter  (Fig.  13-1).  The  biopsy  scar  should  be  oriented  to  be  compatible  with  a  subsequent  wide  local  excision  should  the  lesion  prove  to  be  melanoma.  On  the  extremities  a  longitudinal  or  oblique  incision  is  preferred.  On  the  trunk  or  the  head  and  neck  the  biopsy  should  be  oriented  parallel  to  the  skin  lines.  A  full-thickness  biopsy  should  be  undertaken  in  order  to  accurately  interpret  the  maximum  tumor  thickness,  the  presence  or  absence  of  ulceration,  and  the  level  of  invasion.1
