What do large lymphocytes mean?

Large granular lymphocytes (LGL) are lymphoid cells characterized by either a T-cell or a natural killer (NK) phenotype that physiologically participate in innate immunity and immunosurveillance. Their expansion may be a response to toxic, infectious, and neoplastic conditions, or result from clonal selection (1).

What are the 2 main types of lymphocytes?

There are two major types of lymphocyte: B lymphocytes, which mature in the bone marrow; and T lymphocytes, which mature in the thymus. The bone marrow and thymus are thus known as the central or primary lymphoid organs.

How to confirm a diagnosis of LGL leukemia?

To help confirm a diagnosis, your doctor may examine your blood under a microscope. The lymphocyte count may be normal or low (and lymph nodes are not typically enlarged). Patients may have a large number of abnormal cells associated with LGL leukemia. Bone marrow aspiration or biopsy might be necessary to confirm the diagnosis. Flow cytometry can determine if the LGL leukemia cells are T cells or NK cells.
