Under a magnification of 1150X, this photomicrograph reveals some of the histopathology seen in a peripheral blood smear obtained from a patient with both acute leukemia, and infectious mononucleosis. In this particular view, you can see two darkly-stained cells that were labeled as atypical, or reactive lymphocytes, for their morphology differed from that of normal lymphocytes. Note that their nucleus appeared as lobed, and was surrounded by visible cytoplasm. These reactive, atypical lymphocytes, are often seen in infectious mononucleosis, which is a self-limiting infection, caused by the Epstein-Barr virus, unlike the malignant disorder, acute myeloid leukemia.
