Maturation stages in the bone marrow are as follows: stem cell, myeloblast, promyelocyte, myelocyte, metamyelocyte, band and neutrophil.
Laboratory findings reveal a normal WBC count with a left shift; 73 neutrophils, 16 bands and 1 metamyelocyte. ESR and CRP are both elevated at 38 and 12.40 respectively.
The present study also indicates that LD body may also be present inside nonhistiocytic cells like polymorph, metamyelocyte, and therefore vigilant search of the parasite in nonhistiocytic cells should also be done (Figure 4).
