A few days after a young child gets a sore throat, he develops a diffuse blanching erythema with numerous small papules starting at the head and neck, then involving the trunk and extremities, before having the appearance shown in the first image. The rash feels like sandpaper and is easiest to see along the inguinal crease, axillary fold, and antecubital fossa.
