Persistent polyclonal B lymphocytosis with multiple bcl-2/IgH rearrangements: a benign disorder.
The appearance of a chronic B lymphocytosis is usually associated with the existence of an underlying monoclonal malignant condition. However, a few cases of persistent polyclonal B cell lymphocytosis (PPBL), presented in young asymptomatic women with an uneventful course, have been reported in recent years. In these PPBL cases, since the lymphocytes usually display an anomalous morphology, a f...
متن کاملPersistent polyclonal B-cell lymphocytosis.
Persistent polyclonal B-cell lymphocytosis (PPBL) is a rare and recently described entity. PPBL is diagnosed predominantly but not exclusively in women, usually smokers and is characterized by a moderate, chronic and absolute lymphocytosis (> 4 x 109/L). Peripheral blood examination show in all cases atypical binucleated lymphocytes. A polyclonal serum IgM is also associated and HLA-DR7 express...
متن کاملPersistent polyclonal B-cell lymphocytosis.
We document a case of persistent lymphocytosis in which the characteristic binucleated circulating lymphocytes were shown immunologically to be polyclonal B-cells. Cytogenetic and molecular studies failed to show a clonal population. A review of the literature on this rare condition, persistent polyclonal B-cell lymphocytosis, highlights an association with the female sex, HLA-DR7 antigen, smok...

متن کاملPersistent polyclonal lymphocytosis in human immunodeficiency virus-1-infected patients.
In this study we describe the clinical, morphologic, immunologic, and genetic features of a chronic peripheral blood lymphocytosis associated with posttraumatic splenectomy in patients with human immunodeficiency virus-1 (HIV-1) infection. Among a series of 2,365 consecutive HIV-1 seropositive cases investigated, eight patients were selected for the presence of more than 4,000 lymphocytes/mm3. ...
