Answer

Mucous membrane erosions (seen in 90% of cases) generally precede the skin lesions by 1-3 days. The most frequently affected mucosal membrane is the oropharynx, followed by the eyes and genitalia. Oral cavity involvement typically presents as a sore or burning sensation. Intake may be limited because of pain associated with the oropharyngeal lesions.
