eight cases of pll ( seven b-pll , one t-pll ) showed minor morphological deviations from typical pll which may present diagnostic difficulties when studied only at light microscopy : the cells in four of these had some features in common with those of chronic lymphocytic leukaemia ( cll ) , namely round regular nuclei and heavy chromatin condensation , but the nucleoli were larger in the pll cases .
