Results are presented as median (range) and as absolute and relative frequencies. CTCL, cutaneous T-cell lymphoma; CS, Sézary cells; B2MG, beta 2 microglobulin; LDH, lactate dehydrogenase; MF, Mycosis Fungoides; SS, Sézary syndrome. One patient had circulating CD4+ SC, although they represent only 2.9% of CD4+ T cells, 1.8% of lymphocytes, and 0.4% of leukocytes.
