Intravenous immunoglobulin for treatment of toxic epidermal necrolysis.

We report three female patients suffering from toxic epidermal necrolysis, with 30% to 70% epidermal detachment. Alleged causative agents were dipyrone, dibenzazepine, and allopurinol. All patients were treated by intravenous immunoglobulins (IVIG) and survived without further complications, although poor prognostic factors such as concomitant diabetes, large areas of epidermal detachment, and pancytopenia were present. We report these cases with emphasis on the concept that prompt diagnosis, withdrawal of causative drugs, and immediate treatment are imperative for the favorable outcome of the disease. Our patients can be added to the list of those patients who were successfully treated by IVIG, as indicated in this review of the literature.
