Fig. 4: Flow cytometric immunophenotypic analysis of the case shown in Fig. 1.

The lymphoma cells (pink dots) show increased side scatter (SSC) (A), and are positive for CD45 (A), CD4 (B, decreased), CD8 (B), CD3 (C, small subset), CD7 (C), CD2 (D, increased), and CD56 (F, partial), and are negative for CD5 (D), TCR alpha beta (E), and TCR gamma delta (E). The blue dots represent background reactive T cells.
