Figure 1From: A stable aberrant immunophenotype characterizes nearly all cases of cutaneous T-cell lymphoma in blood and can be used to monitor response to therapy Sézary syndrome with multiple immunophenotypic aberrancies in tumor cells. Aberrant events representing neoplastic cells are painted red and normal CD4 and CD8 T-cell populations are painted green. A. Tumor cells are CD3 bright(+)CD45 dim(+). B. They are also CD4 dim(+)CD7 bright(+) phenotype and are separable from the normal CD4(+) T-cell population. C Tumor cell population is CD4 dim(+) CD26(-).Back to article page
