Toxic epidermal necrolysis-like acute cutaneous lupus erythematosus: two cases report.

Toxic epidermal necrolysis-like acute cutaneous lupus erythematosus (TEN-like ACLE) is a rare manifestation of systemic lupus erythematosus (SLE). Because of its rarity, little is known about this entity. In this report, we describe a case of two women previously diagnosed with SLE that presented TEN-like skin lesions. The common elements in both patients were the initial disposition of the lesions on the photoexposed areas, the positivity of Nikolsky´s sign, the discrete mucosal attrition compared to that observed during TEN, and the simultaneous appearance of dermatological lesions with an extra-cutaneous flare of lupus disease. The skin biopsy in both cases showed epidermal necrosis with an identification of lupus band on direct immunofluorescence. Systemic corticosteroids were used with a good evolution after 2 weeks. Skin damage is an indicator of disease activity, and careful search for extracutaneous involvement is obligatory to prevent further complications.
