Content: The most alarming cause of an elevated WBC count is leukemia—cancer of the bone marrow or lymphatic tissues. Different types of leukemia elevate different types of WBCs and are also marked by the appearance of immature forms of WBCs in the bloodstream—forms that would otherwise be seen only in the bone marrow. Here are some photos that illustrate these points. Normal blood film. Here we see only four WBCs amid numerous red blood cells (the pink discs) and scattered platelets (small pink and violet dots). Mononucleosis. This shows an overabundance of a WBC type called monocytes, with large, rounded, unsegmented nuclei. A leukocytosis that was diagnosed as chronic myelogenous leukemia (CML) in a 57-year-old man. Notice the far greater number of mature and immature WBCs. This would call for a bone marrow biopsy for further diagnostic information.
