title: Lymphocytosis of large granular lymphocytes associated with anemia and neutropenia: proof of monoclonality of the LGL-population, but benign clinical course.
abstract: A 37-year-old man with severe transfusion-requiring anemia and neutropenia associated with lymphocytosis of large granular lymphocytes (LGLs) has been followed over a period of 3.5 years. Detailed phenotyping of the LGL has been performed, revealing a phenotype of CD3+, CD8+, CD16+, HLA-DR+, and Leu-7+. Southern-blot analysis of the T-cell receptor beta-chain locus detected a gene rearrangement, thus providing proof of monoclonality of the peripheral blood LGLs.
