Lupus erythematosus and epidermal necrolysis: a case series of 16 patients.

Abstract

Epidermal necrolysis (EN, including Stevens-Johnson syndrome and toxic epidermal necrolysis (TEN)) is mostly induced by drugs. Prevalence of lupus erythematosus (LE) is higher in EN than in general population (1.2 to 2%).1,2 Furthermore, flares of LE may present as EN (TEN-like LE).3-5 We aimed to describe EN in patients with clinical or biological LE to better characterize the relation between both diseases.
