Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis–Like Lupus Erythematosus, Background/Objective Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN)–like lupus erythematosus is a hyperacute and life-threatening form of cutaneous lupus erythematosus. Because of its rarity, little is known about this entity. We aimed to evaluate the clinical characteristics, laboratory findings, systemic manifestations, treatments, and outcome of SJS/ TEN-like lupus erythematosus. Methods We conducted a chart review study from July 2002 to September 2016 of all patients diagnosed with SJS/TEN-like lupus erythematosus who presented with gradual epidermal necrolysis without clear drug or infectious culprit. We evaluate for clinical features, extracutaneous involvement, Systemic Lupus Erythematosus Disease Activity Index, histologic findings, immunofluorescence pattern, serologic abnormalities, treatment, outcome, and recurrence of SJS/TEN-like lupus erythematosus. Results Of 9074 patients diagnosed with cutaneous lupus erythematosus and/or systemic lupus erythematosus, 6 patients justified the diagnosis of SJS/TEN-like lupus erythematosus (5 SJS/TEN-like acute cutaneous lupus erythematosus, 1 TEN-like subacute cutaneous lupus erythematosus), accounting for 0.07%. Fifty percent had epidermal necrolysis as the initial presentation of lupus with a median time from onset of 1.5 months (0–48 months). The median duration between initial rash and epidermal detachment was 4.5 days (3–14 days). All had internal organ involvement (hematologic and renal) and high Systemic Lupus Erythematosus Disease Activity Index score (median, 19.5 [16–24]). Most recovered with systemic corticosteroids, antimalarial drugs, and/or immunosuppressants. None had disease recurrence. Conclusions This is the largest single series of patients with SJS/TEN-like lupus erythematosus. Skin damage is an indicator of disease activity, and careful search for extracutaneous involvement to prevent further complications is mandatory.
