Prolymphocytic leukaemia--report of three cases.

Prolymphocytic leukaemia is a rare subtype of chronic lymphocytic leukaemia. Three such cases were reported here along with clinical details. All these cases were seen in males above 5th decade. These patients showed moderate to massive splenomegaly, inconspicuous lymphadenoapthy in two cases and one with minimal lymphadenopathy. Peripheral smear showed high leukocyte count with more than 55% of prolymphocytes. Bone marrow aspiration showed diffuse involvement and in one with minimal lymphadenopathy, lymphnode aspiration showed prolymphocytes. All the three patients died within a year after diagnosis.
