Bone marrow examination showed marked hemophagocytosis in a reactive marrow with normal megakaryocyte precursors.
Cortical erosions, asymmetric edema on one side of the joint, and extensive marrow involvement suggest osteomyelitis rather than reactive marrow edema (Figure 7).
Morphological tinclings of pathological "clonal" blasts (type II that contain Auer rods, Pseudo-Chediak-Higashi or other specific inclusions that are not seen in reactive marrow) refer to the diagnosis of RAEB-2 or AML; here again the arbitrary cut-off point of 20% blasts results in a specific diagnosis.
His bone marrow aspirate was cellular with signs of reactive marrow. His serum samples were tested by aldehyde test, anti-rK39 dipstick test (Insure[TM], In-Bios Int., USA), rKE16 latex agglutination test, and anti-rKE16 spot test (Signal KA[TM], Span Diagnostics Limited, India).
