Case report: oxaprozin and fatal toxic epidermal necrolysis

We have presented a case of fulminating TEN with a fatal outcome. We believe there is strong probability that the TEN was caused by a propionic acid NSAID oxaprozin. This is the first reported case of TEN related to this particular agent. Toxic epidermal necrolysis has been reported with all types of NSAIDs. It appears from this case that switching from one class of nonsteroidal anti-inflammatories to another is not always without risk. Despite the class of nonsteroidal anti-inflammatory agent used, the possibility of systemic reaction cannot be excluded.
