Vancomycin-induced toxic epidermal necrolysis.

We have reported a patient who had had renal transplantation for end-stage renal disease; she was treated for fever and presumed sepsis with intravenous tobramycin and vancomycin, with subsequent development of persistent fever, eosinophilia, and a maculopapular rash that progressed to linear bullae. Findings on skin biopsy were consistent with a diagnosis of toxic epidermal necrolysis. Sustained measurable serum concentrations of vancomycin, the temporal response to drug exposure, and the response to steroid therapy suggest vancomycin as the causative agent.
