Diagnosis of B-Cell Non-Hodgkin Lymphomas with Small-/Intermediate-Sized Cells in Cytopathology

Figure 5

Fine needle samples of chronic lymphocytic leukemia/small lymphocytic lymphoma examined after Papanicolaou stain. Several ill-defined cellular aggregates (circle) are visible at low power inspection giving the impression of vague nodularity (a). High-power examination reveals the peculiar chromatin distribution and presence of numerous prolymphocytes (red arrowheads) within this area of increased cell density (b). Note the coarse distribution of the chromatin and tinctorial quality of the nucleoli in the prolymphocytes in this stain. ((a) and (b): Papanicolaou; (a): 10x, (b): 63x).
