AB Purpura  is  extravasation  of  red  blood  cells  into  the  skin  or  mucous  membrane.  For  this  reason,  purpuric  lesions  do  not  blanch  on  diascopy  (pressing  on  the  lesion  with  a  glass  slide  or  finger).  The  differential  diagnosis  for  purpura  is  broad,  but  it  can  be  quickly  narrowed  by  classifying  the  lesions  based  on  their  morphology,  as  well  as  other  clinical  and  laboratory  findings.1,2  The  clinical  descriptive  terms  for  purpura  are  listed  below,  and  their  respective  tables  describing  the  differential  diagnosis  are  referenced.
