Phenytoin-Associated Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis Overlap in Focus: A Case Report.

Stevens-Johnson syndrome and toxic epidermal necrolysis overlap is a rare but severe cutaneous hypersensitivity reaction that can lead to death if not treated aggressively and adequately. Drug-induced hypersensitivity reactions are often related to drug exposure, with sulfonamides, anti-epileptics, fluoroquinolones, cephalosporins, and nonsteroidal anti-inflammatory drugs being the most common culprits. This case report describes a 10-year-old boy who was administered phenytoin at a local clinic to manage his seizures. This treatment led to the onset of SJS-TEN overlap, ultimately resulting in his demise.
