A 77-year-old female patient with symptomatic atrial fibrillation with fast ventricular rate despite conventional antiarrhythmic therapy was treated with dronedarone. Five days later, she developed a maculopapulous exanthema and small flaccid blisters, which spread over the common integument predominantly located on the dorsal trunk. Over few days, the patient showed a severe epidermal necrolysis of approximately 30 % of the body area and ultimately died in multiorgan failure. Here, we report a rare case of toxic epidermal necrolysis during treatment with dronedarone leading to patient death.
