Three atypical lymphocytes and one normal lymphocyte are shown on a blood smear film. These WBCs are "atypical" because they appear larger (more cytoplasm) and have nucleoli in their nuclei compared to a normal lymphocyte. Their cytoplasm tends to be indented by surrounding red blood cells. Such atypical lymphocytes are often associated with infectious mononucleosis from Epstein-Barr virus (EBV) infection.
