A classic skin finding in erythema multiforme is what?

• A. Bullae
• B. Pustules
• C. Target lesions
• D. Urticaria

Answer: (C)

Erythema multiforme is classically defined by target lesions—iris- or bull’s-eye shaped eruptions with concentric color zones. A typical lesion has a central dark or vesicular area, a pale edematous band, and an outer bright red ring. These lesions frequently appear on the hands and feet and may appear on other extensor surfaces, with mucosal involvement possible in more extensive cases. This distinctive target pattern is the hallmark finding and helps distinguish EM from other rash types. Bullae are large blisters seen in other conditions, pustules are pus-filled lesions seen in different inflammatory or infectious processes, and urticaria presents as transient wheals rather than fixed concentric lesions.
