AB Purpura,  or  bleeding  into  the  skin,  may  be  an  innocent  finding  in  minor  trauma  or  the  first  sign  of  a  life-threatening  disease.  Pinpoint  areas  of  hemorrhage  are  called  petechiae;  large,  confluent  patches  are  referred  to  as  ecchymoses.  Purpura  may  result  from  extravascular,  intravascular,  or  vascular  processes.  Nonpalpable  purpuric  lesions  develop  from  extravascular  and  intravascular  phenomena,  whereas  those  that  are  palpable  result  from  a  vascular  process.  Conditions  associated  with  each  type  are  listed  in  Table  58-1.
