Bone marrow smears shows an infiltration by tumour lymphocytes which is not uniform (as it would be in the classic variant of CLL). In this case of an atypical pleomorphic variant of CLL, more than 10% of tumour cells have a different appearance than typical small lymphocytes, which generally show clumped chromatin and scanty cytoplasm.

This is particularly the case when the cells in question are large or “big blue” cells. Refer to the diagnostic algorithm and table in the related links below for help to determine if a large mononuclear cell with blue cytoplasm is a reactive lymphocyte or a neoplastic “blast”. These atypical lymphocytes morphologically appear the same as those found in adults. 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.

Some, like the flu or mild infections, aren’t serious for most people. Lymphocytosis results from increased numbers of lymphocytes in your blood. Lymphocytes are a type of white blood cell. They play an important role in your immune system, helping your body fight off infection.

In contrast, the cell depicted in Image BCI-10 is a reactive. (also called atypical or variant) lymphocyte. Although there are no “typical” atypical lymphocytes,

These cells have ample basophilic cytoplasm but retain the "clumped" nuclear chromatin pattern characteristic of lymphocytes. Download Image 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. The nucleus of a reactive lymphocyte can be round, elliptic, indented, cleft, or folded. The variety of morphologic appearances among the reactive lymphocytes presented in this testing event is also characteristic of a benign lymphoproliferative disorder such as infectious mononucleosis.

normal lymphocyte in picture BCI-03, it is larger and has a darker blue cytoplasm. Likewise, though the reactive features in the lymphocytes in BCI-04, BCI-05, and the additional lymphocyte in BCI-06 are variable, it is this heterogeneity that defines these cells as “variant.” The lymphocyte in BCI-04 has

The pleomorphic variant with prolymphocytic features is observed in extremely rare cases of mantle cell lymphoma. This peripheral blood smear shows a mixed, highly pleomorphic population of neoplastic lymphocytes. Many tumour cells are medium-sized or large atypical lymphocytes with abundant pale or slightly basophilic cytoplasm and very irregular "floral pattern" shape of the nucleus (blue Clinical laboratory and biomedical science related news, abstracts and images for medical laboratory professionals, students and other laboratory geeks.
