Lamotrigine-induced erythema multiforme mimicking contact dermatitis.
Erythema multiforme is an acute, hypersensitivity reaction of the skin often secondary to medications. Lamotrigine is a relatively new anticonvulsant medication approved for seizure and psychiatric disorders. Although the overall incidence of cutaneous reactions to lamotrigine is high, the incidence of serious eruptions such as erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis is low. Vigilant surveillance for any cutaneous eruption in patients on lamotrigine is important, particularly in the first 8 weeks, as prompt discontinuation of the medication can prevent progression. We report a case of erythema multiforme secondary to lamotrigine, which clinically resembled a contact dermatitis, and review the management of lamotrigine associated cutaneous eruptions.
