Initial presentation includes fever, malaise, and irritability following an upper respiratory infection with pharyngitis or conjunctivitis. Patients first develop a diffuse faint blanching erythematous rash that is tender to the touch. Crusting around the mouth, eyes, and neck may be seen. Within 2 to 3 days, flaccid blisters and bullae develop, especially in flexor creases and the buttocks, hands, and feet. These bullae are sterile. In some patients, widespread desquamation occurs. The differential diagnosis includes toxic epidermal necrolysis, exfoliative erythroderma, bullous erythema multiforme, bullous pemphigoid, bullous impetigo, sunburn, enterovirus, drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome, acute mercury poisoning, toxic shock syndrome, and epidermolysis bullosa.
