KIR3DL2 was reported as a sensitive diagnostic factor and also associated with reduced disease-specific survival for CD3+ T cells in peripheral blood of Sezary syndrome (SS), a leukemic form of cutaneous T cell lymphoma (CTCL) [21] and expressed in 65.7% CTCL skin biopsies [22]. Here, KIR3DL2 is linked to primary cutaneous T-cell non-Hodgkin lymphoma.
