The  field  contains  two  eosinophils,  two  neutrophils,  and  a  lymphocyte.  The  eosinophils  are  typical  cells;  bilobed  nucleus,  present  in  virtually  all  normal  eosinophils,  and  a  cytoplasm  filled  with  eosinophilic  granules.  The  granules  do  not  obscure  the  nucleus  as  is  characteristic  in  basophils.  Some  small  areas  without  granules  (degranulation)  are  present.  Note  that  the  neutrophil  granules  are  too  small  to  be  resolved  by  the  light  microscope,  whereas  the  large  eosinophilic  granules  can  be  resolved.  This  is  especially  evident  if  eosinophilic  granules  are  released  from  disrupted  cells  and  are  free  in  the  surrounding  area.
