case_images: A male patient in his 60s was admitted to our hospital after experiencing widespread erythema with blister formation, skin pain, and mucosal detachment for 5 days ( Figure 1A  ) and showed no improvement after receiving methylprednisolone (4 mg/kg/d) and intravenous immunoglobulin (IVIG) (0.4 g/kg/d) treatment for 3 days. The Severity-of-Illness Score for TEN (SCORTEN) of 5 was calculated based on objective parameters recorded by dermatologists experienced in managing TEN upon admission ( Figure 1B  ). The total area of detachment (including Nikolsky's sign-positive areas) accounted for 67%.
