A homogeneous diffuse abnormal lymphoid infiltrate scattered within which are numerous tingible body macrophages giving the classic “starry sky” appearance (hematoxylin and eosin, × 10). B. The abnormal lymphoid cells are medium-sized blasts with prominent apoptotic bodies, some of which are contained within the large tingible body macrophages (hematoxylin and eosin, × 60). C. CD20 immunophenotyping demonstrates B-cell lineage (immunoperoxidase, × 60). |
