Atypical lymphocytes

Some changes can occur in lymphocytes, such as primitive cellularization and naive cellularization (commonly known as "return to the ancestors"). Such changes are usually stress reactions caused by viruses or drugs. Under the microscope, the volume of the cells becomes larger, the volume of the nucleus increases, the color of the cytoplasm deepens, and vacuoles appear. This is significantly different from normal lymphocyte morphology. At this time, atypical lymphocytes should be reported.
