PB morphology of 4 different B-cell leukemias. (A) B-PLL, showing monomorphic prolymphocytes (PL) with condensed chromatin, prominent nucleolus, and scanty basophilic cytoplasm. (B) CLL/PL showing a single prolymphocyte (PL), and several typical CLL cells, which are half the size of the PL, have less cytoplasm and no nucleolus. (C) HCL-V showing cells with condensed chromatin and a conspicuous single nucleolus, but with more abundant pale cytoplasm with cytoplasmic projections. (D) SMZL showing lymphocytes with short polar villi and basophilic cytoplasm.
