Erythema multiforme (EM) is a skin condition due to an immune-mediated hypersensitivity reaction to infections or drugs.12 It presents as a dermatological eruption featuring iris or target lesions, although other forms of skin lesion can occur - hence the name. It is usually an acute, self-limiting disease that affects the skin. Mucosal lesions are present in 25% to 60% of patients with erythema multiforme.
