Abstract

Prolymphocytic leukemia (PLL) first described by Galton and colleagues in 1975; is a distinct clinicopathologic variant of chronic lymphocytic leukemia. It is characterized by marked lymphocytosis; massive splenomegaly; minimal lymphadenopathy; and poorrognosis. The clinical course of PLL is generally brief; the median survival in Galton's original series was 4 months. We experienced a case of B-prolymphocytic leukemia. The patient was a 64 year-old man who presented with splenomegaly; marked leukocytosis and 65% of characteristic prolymphocytes in the peripheral blood. We report a case of PLL with a prolonged course after combination chemotherapy with daunorubicin; L-asparaginase; vincristine; prednisolone; and methotrexate.
