An extremely rare mucocutaneous adverse reaction following COVID-19 vaccination: Toxic epidermal necrolysis.

Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN), is a type of delayed hypersensitivity reaction that requires urgent medical intervention. In the COVID-19 era, COVID-19 vaccines are currently being widely administered and mucocutaneous adverse reactions following vaccination have been reported; however, severe cutaneous adverse reactions associated with COVID-19 vaccines including SJS/TEN, are extremely rare. Herein, we describe a case of COVID-19 vaccination induced TEN which developed 1 day after receiving the first dose of Sinopharm COVID-19 vaccine with favorable clinical outcome.
