UBXN11 and toxic epidermal necrolysis: We have suspected that the pathogenesis of SJS/TEN with SOC is different from the pathogenesis of SJS/TEN without SOC (Ueta and Kinoshita, 2012), since major causative drugs for SJS/TEN with SOC were different from those for SJS/TEN without SOC, and the HLA association with SJS/TEN with SOC was different from SJS/TEN without SOC.
