WebThe atypical lymphocyte is almost as big as the monocyte; however, the nucleus is more regular. What is the difference between atypical and reactive lymphocytes? Reactive, or atypical, lymphocytes are relatively fragile cells, and as a result can be squeezed out of shape by surrounding cells, giving them a scalloped appearance instead of a smooth cytoplasmic edge. The nucleus of the reactive lymphocyte is larger than that of the small Mayo Clinic offers appointments in Arizona, Florida and Minnesota and at Mayo Clinic Health System locations.
