AB A  71-year-old  woman  presented  with  a  rapidly  growing  lesion  on  her  face  over  the  past  4  months  (Figure  174-1).  The  lesion  had  features  of  a  basal  cell  carcinoma  with  a  pearly  border  and  telangiectasias  (Figure  174-2).  Also,  the  central  crater  with  keratin  gave  it  the  appearance  of  a  keratoacanthoma  (KA).  A  shave  biopsy  was  performed,  and  the  pathology  showed  squamous  cell  carcinoma  (SCC)–KA  type.  A  full  elliptical  excision  with  4-mm  margins  was  then  performed.
