Abstract
En 中文
Erythema multiforme is an inflammatory skin and mucosal disease mainly related to infectious agents such as Herpes simplex virus, Mycoplasma pneumoniae, though it can also be idiopathic . The characteristic skin lesions are typical or atypical acral raised target lesions. The oral mucosa can be affected, alone or in combination with other mucosal/cutaneous sites, sometimes causing extreme pain, severely impacting food intake, and warranting hospitalization. A comprehensive understanding of erythema multiforme clinical characteristics, triggering agents, and differential diagnosis including Stevens-Johnson syndrome/Toxic Epidermal Necrolysis, is crucial to conduct proper workup and management. Mycoplasma pneumoniae infection should be immediately ruled out because of the need of antibiotics. The cornerstone of management is symptomatic treatment and will be detailed in this review as well as the etiologic treatment. Lastly, the management of persistent or recurrent erythema multiforme can be challenging, especially when antivirals fail to prevent a relapse, but breakthrough treatments have been reported successful in this difficult-to-treat subset of patients.
