Transformation of CLL into other B-LPDs (prolymphocytic leukaemia (PLL) and large cell lymphoma) is a well recognised phenomenon. One previous report has suggested that HCL may also arise by clonal evolution from CLL. We report the case of a 75 year old man in whom a diagnosis of coexisting HCL was… CONTINUE READING
