The pan T cell markers is usually expressed, but many times one of the T cell markers is aberrantly negative or underexpressed. CD7 is usually expressed on LGL. The NK markers CD56 and CD16 are usually expressed on about 1/3 of these cases. Large granular lymphocyte (LGL) leukemia is a rare cancer that affects your white blood cells; fewer than 1,000 people each year are diagnosed with LGL leukemia. What these hundreds of people experience, however, is not the same for the thousands diagnosed with other forms of leukemia. LGL syndrom defineres som en neoplastisk sykdom (REAL klassifikasjon) med kronisk økt antall store granulære monoklonale lymfocytter (hvite blodlegemer) (CD3+ cytotoksiske NK-celler) i blod og benmarg.

1 It is a rare disease with an incidence of 0.2 cases per 1 million individuals per year and represents 2% to 5% of chronic lymphoproliferative diseases in the US. 2 The median age at diagnosis is 66.5 If diagnoses other than LGL leukemia are being considered (for example: myelodysplastic syndrome, aplastic anemia, pure red cell aplasia). If the number of LGL cells in the blood is not increased but other features are consistent with the diagnosis of LGL leukemia, then a bone marrow aspirate and biopsy can show that there is a clonal LGL cell population in the bone marrow.

Clonality can be confirmed by detection of T cell receptor (TCR) gene rearrangements. The other form of LGL leukemia is categorized as a chronic lymphoproliferative disorder of NK cells, with increased numbers of clonal NK cells in circulation. LGL leukemia arises most frequently from a T cell lineage (85 percent) or, less commonly, from a natural killer (NK) cell lineage (15 percent) . The etiology, clinical features, diagnosis, and treatment of NK cell LGL disorders will be discussed here. T cell LGL leukemia is discussed separately. Large granular lymphocytic (LGL) leukemia is a rare lymphoproliferative disorder defined by monoclonal proliferation of mature T cells or natural killer cells. In 1993, LGL leukemia was divided into two subtypes: T-cell LGL (T-LGL) leukemia and NK-cell leukemia, later recognized by the World Health Organization in … T-cell large granular lymphocyte leukemia (T-LGL) is characterized by a persistent increase in the number of peripheral blood (PB) large granular lymphocytes (LGL) over a sustained period (usually > 6 months), with absolute T-LGL counts between 2- 20 X 10 9 /L, without a clearly identified cause(1).
