AB  - Extravascular  (hemorrhagic)  oral  lesions  are  purplish/red  discoloration  of  the  oral  tissue  due  to  the  extravasation  of  blood.  The  lesions  can  be  divided  based  on  size  into  petechiae  (1-  to  2-mm  pinpoint  red  areas),  purpura  (  1  cm).  The  lesions  are  usually  the  result  of  trauma  but  may  also  be  a  manifestation  of  platelet  disorders  (thrombocytopenia),  leukemia,  vascular  disorders  (vasculitis),  and  coagulation  disorders  (scurvy,  disseminated  intravascular  coagulation).  The  most  common  sites  are  the  ones  most  susceptible  to  trauma,  such  as  the  tongue,  buccal  mucosa,  and  palate.
