Abstract:

We present a case of persistent polyclonal B-cell lymphocytosis (PPBL). This syndrome is characterized by a persistent lymphocytosis with circulating atypical binucleated lymphocytes. The patient had serological evidence of a previous EBV infection, had raised polyclonal serum IgM levels and was a heavy smoker. No malignancy was detected.
