Histological and immunohistochemical features of the spleen in persistent polyclonal B-cell lymphocytosis closely mimic splenic B-cell lymphoma
UNLABELLED Persistent polyclonal B-cell lymphocytosis (PPBL) is rare and intriguing hematological disorder predominantly reported in young to middle- aged smoking women. It is characterized by persistent moderate polyclonal B-cell lymphocytosis with circulating hallmark binucleated lymphocytes and elevated polyclonal serum IgM. Most patients have benign clinical course on long-term follow-up. S...
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).

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 B Cell Lymphocytosis B Cells Can Be Activated through CD40-CD154 Interaction
Persistent polyclonal B cell lymphocytosis (PPBL) is a rare disorder, diagnosed primarily in adult female smokers and characterized by an expansion of CD19(+)CD27(+)IgM(+) memory B cells, by the presence of binucleated lymphocytes, and by a moderate elevation of serum IgM. The clinical course is usually benign, but it is not known whether or not PPBL might be part of a process leading to the em...
