Thus, they are more frequently in younger animals, who are antigenically naive. Any disease process can induce antigenic stimulation and result in the presence of reactive lymphocytes in circulation, thus it is a relatively non-specific finding. 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 lymphocyte, and is more irregular in shape. Sometimes it is rounded, oval or indented with a typical “stretched • describe characteristic morphologic findings associated with reactive lymphocytes. • compare morphologic features of normal lymphocytes, reactive lymphocytes, and monocytes. Photograph BCI-01 shows a reactive lymphocyte.

Atypical lymphocytes, or “variant” lymphocytes as they are currently referred to, are defined as non-malignant lymphocytes that are in response to non-specific hematopoietic stress as seen with various conditions/disorders. Reactive lymphocytes or variant lymphocytes are cytotoxic (CD8 +) lymphocytes that become large as a result of antigen stimulation. Typically, they can be more than 30 μm in diameter with varying size and shape. Variant lymphocytes Author: Peter Maslak, 11/01/2009 Category: Laboratory Hematology > Basic cell morphology > Morphologic variants of white blood cells > Myeloid leukocytosis What should you know about atypical lymphocytes?

Atypical lymphocytes can be defined as those lymphocytes that are larger than normal and respond superiorly to antigen exposure. This type of cells can be round, indented, elliptical or even folded. In general, the size of the lymphocytes is more than 30 microns. Lymphocytes play an important role in the immune response of the body.

This condition may also be because of some auto-immune disorders like Rheumatoid arthritis. Lymphs are lymphocytes, a type of white blood cell.
