Background: Toxic epidermal necrolysis is an acute mucocutaneous reaction characterized by extensive cutaneous and mucosal sloughing and systemic involvement. It is generally associated with drug ingestion.
Objective and methods: We describe 2 patients who developed typical clinical and histopathologic features of toxic epidermal necrolysis with unusual subacute progression, absence of systemic involvement or high-risk drug ingestion, and features of lupus erythematosus.
Conclusion: We propose that this constellation of features represents a new entity not previously described. This entity may represent a more severe variant of Rowell's syndrome or, alternatively, a novel manifestation of lupus erythematosus
