Unlike most forms of leukemia the pattern of bone marrow infiltration in TLGL may be subtle and the cytopenias are often lineage specific with neutropenia dominating. Gaslini Università degli Studi di Genova.

To assess whether the HLADR4 association found in rheumatoid arthritis RA is also seen in the large granular lymphocyte LGL syndrome. Large granular lymphocyte LGL leukemia features a group of indolent lymphoproliferative diseases that display a strong association with various autoimmune conditions. Large granular lymphocyte leukemia LGL is a lymphoproliferative disorder marked by clonal expansion of large granular lymphocytes usually T.

Due to the lack of a single unique genetic or phenotypic feature and clinicopathological overlap between reactive and neoplastic entities accurate LGL syndrome. Transient Large Granular Lymphocytosis is a short-term increase in large granular lymphocyte numbers usually less than 6 months that may be seen in association with a variety of conditions including viral infections autoimmune disorders and non-lymphoid malignancies. Short report Haematologica 1995.
