Title: Abnormal expansions of granular lymphocytes: reactive lymphocytosis or chronic leukemia? Case report and literature review. Author: Gastl G, Rumpold H, Kraft D, Gattringer C, Schuler G, Margreiter R, Schmalzl F, Huber C. Journal: Blut; 1986 Feb; 52(2):73-89. PubMed ID: 2936412. Abstract: A case of chronic lymphoproliferative disorder is presented, wherein a morphologically homogeneous population of lymphoid cells displayed properties similar to those described for large granular lymphocytes (LGL). Besides their LGL-like phenotype (VEP 13+, OKM 1+, OKT 10+ Fc-IgG-receptor+, OKT 3-), the proliferating cells were cytotoxic to NK targets as well as to antibody-coated target cells. Clinically, our patient presented low-grade lymphocytosis, splenomegaly, neutropenia, hyperimmunoglobulinemia and recurrent infections. Based upon this and 32 similar cases reported in the literature, we conclude that lympho-proliferative disorders involving GL encompass a variety of clinical entities, ranging from reactive GL lymphocytoses to overt lymphocytic malignancies.[Abstract] [Full Text] [Related] [New Search]
