Immune phenotyping impacts on management of severe cutaneous adverse reaction

The pathogenesis of SCAR remains unclear, and most effective therapeutic strategy has not yet been established. However, the pathogenesis of keratinocyte cell death in SJS/TEN, which is the most critical phenomenon, has been established. The difference of immune profile between early and late stage have been suggested in DIHS/DRESS. Although new therapeutic options have been identified by resent studies, there is a lack of trial data for the efficiency of them. Further trials and studies of SCAR is expected to lead to the development of general effective treatment options for SCAR.
