Cutaneous T cell lymphomas are a heterogeneous group of non-Hodgkin’s lymphomas derived from the population of T cells that home to and inhabit the skin. There have been conflicting reports as to whether CTCL may represent a malignancy of regulatory T cells, a particular T cell subset that can suppress local immune reactions. In this issue of the JID, authors Heid et al. present convincing evidence that the malignant T cells in a specific subgroup of Sézary patients are FOXP3+ regulatory T cells. Clonal malignant T cells in these patients have increased expression of the Treg associated transcription factor FOXP3, demethylation of the FOXP3 gene locus, and T cells from at least some of these patients could suppress T cell proliferation in vitro.
