Determining the true cause of death in a dermatological disaster.
Adverse drug reactions that result in patient death warrant special consideration to determine if the outcome was preventable. We report the results of an investigation into the cause of death of a 63 year old male who was thought to have phenytoin-induced toxic epidermal necrolysis (TEN). Most dermatological reactions from drugs are minor and resolve without sequelae once the drug is discontinued. In some cases, reactions are severe and can be life threatening. The patient arrived at the emergency department with extensive exfolative dermatitis. The differential diagnosis included phenytoin-induced TEN, scalded skin syndrome, and phenytoin hypersensitivity. After he was admitted his clinical status deteriorated and he died 13 days after admission. Autopsy findings were significant for necrotizing dermatitis, necrotizing pneumonia, multiple herpetic ulcerations, multisystem organ failure and blood cultures grew Staphylococcus aureus (TSS toxin positive). Findings that indicate a cause of death other than a drug-induced dermatological reaction are presented as well as an overview of the patients' medical history. The differential diagnosis of drug induced skin lesions are also discussed.
