Evaluation of patients with erythema exudativum multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis treated at our department during the previous 9-year period

Erythema exudativum multiforme (EM), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN) are acute inflammatory diseases of the skin and mucous membranes. EM with mucosal eruptions is sometimes difficult to differentiate from SJS or TEN. This study aimed to understand the characteristics of these diseases by evaluating the backgrounds, clinical symptoms, and disease courses of EM/SJS/TEN patients treated at our hospital. It shows that persistent fevers and erosion are common in SJS/TEN. Therefore, we must pay attention to whether they become more severe.
