Fat  cells  are  the  clear  ovoid  or  circular  spaces  and  compose  about  three-quarters  of  the  area  of  this  section.  Most  of  the  remaining  area  is  a  clear  pink  matrix.  No  megakaryocytes  are  evident.  Hematopoietic  cells  are  profoundly  decreased  in  number.  In  the  aplastic  marrow  most  of  the  cells  are  lymphocytes  and  occasional  plasma  cells.  Rarely,  “hot  spots”  are  seen  in  aplastic  marrow.  These  are  very  infrequent  areas  of  residual  hematopoietic  cells.
