“…Both processes involve increased circulating CD8 + T cells; in HLH, CD8 + T cells are unable to be downregulated, whereas in SJS/TEN they are inappropriately activated, leading to keratinocyte apoptosis 3 Table IIDocumented cases of SJS/TEN complicated by HLHPatient | Suspected trigger | Pertinent history | Treatment of HLH | Outcome |
