• Very rare in adults.
• Found on the trunk and upper arms and legs, but almost never on the face.
• The rash appears as pink or red macules (flat spots) or papules (small lumps), which spread outwards in a circular shape.

• Dysphagia, regurgitation, and noncardiacchest pain

• TEN involves more than 30% of the body surface, whereas SJS involves less than 10% .
