Toxic epidermal necrolysis following morbilli-parotitis-rubella vaccination

We present the first reported case of toxic epidermal necrolysis (TEN) caused by morbilli-parotitis-rubella (MPR) vaccine. A 13-year-old girl developed TEN 7 days after she received live, attenuated, triple MPR vaccine. The history of drug intake and any illness was negative. At admission the patient was acutely ill with high fever. The whole body was erythematous. The epidermis was wrinkled and the Nikolsky sign was positive. Numerous erosions were present on the lips and genital region. On the seventh day of illness, the eruption involved 80% of the skin. Systemic corticosteroid therapy was not employed. The skin and mucosal defects completely epithelized by the end of the third week of illness. Mild keratoconjunctivitis sicca remained because of permanent cup cell damage.
