AB Thrombocytopenia  occurs  in  40%  to  70%  of  all  HIV  patients.  It  can  occur  independently  at  all  stages  of  HIV  infection  and  may  be  encountered  as  the  initial  presentation  of  disease.  HIV-associated  anemia  and  granulocytopenia  can  occur  concomitantly  as  the  course  of  the  HIV  infection  worsens,  with  thrombocytopenia  seen  in  30%  of  patients  with  CD4  counts  less  than  200/mm3.  HIV  patients  with  thrombocytopenia  often  present  to  the  ED  with  bleeding  (especially  from  the  oral  mucosa),  ecchymosis,  and  petechiae.  Secondary  causes  of  thrombocytopenia  are  generally  seen  as  the  result  of  opportunistic  infections,  malignancy,  or  medications.
