ABSTRACT
Persistent Lymphocytosis
Persistent Polyclonal Binucleated B-cell Lymphocytosis (PPBL) is a rare, benign hematological disorder characterized by a chronic polyclonal B-cell lymphocytosis with binucleated lymphocytes. We report the clinical case of a young woman with lymphocytosis who presented binucleate lymphocytes at the morphological examination of the peripheral venous blood smear. Flow cytometry immunophenotyping performed in peripheral blood showed a polyclonal lymphocyte B subpopulation. Serological tests were negative for viral infections. Because of its benign and indolent course, the diagnoses of PPBL is important in order to avoid unnecessary diagnostic procedures and therapies.
