The physician thought that this was most likely toxic epidermal necrolysis (TEN). He was in a small hospital without a burn unit, so he drew baseline labs and blood cultures, and started to give intravenous fluids to treat the dehydration.
TEN is on the most severe side of a spectrum of disorders that includes erythema multiforme and Stevens-Johnson syndrome (SJS). Erythema multiforme is diagnosed when < 10% of the body surface area is involved, SJS/TEN when between 10% and 30% is involved, and TEN when >30% is involved. Drugs that are most commonly known to cause SJS and TEN include sulfonamide antibiotics, allopurinol, nonsteroidal anti-inflammatory agents, amine antiepileptic drugs (phenytoin and carbamazepine), and lamotrigine. In this case, the amoxicillin was the likely culprit.
The physician waited until the patient was hemodynamically stable before transferring her to the closest city hospital where a dermatologist could manage her care. The dermatologist agreed with the diagnosis of TEN and continued supportive care. While the hospital did not have intravenous immunoglobulin or cyclosporine on hand, the health care team was able to provide the necessary supportive care. The patient survived, and she was warned to never take any type of penicillin again.
