Drug-induced subacute cutaneous lupus erythematous from cenobamate: case presentation and review of the literature.

A 68-year-old woman with a history of seizures on cenobamate presented with an itchy rash all over her body. The rash started about one month prior to her presentation to the dermatology clinic. The rash was initially treated with topical triamcinolone with improvement at one-month follow-up. However, four months later the rash flared and there was concern that cenobamate was the cause. Biopsy was performed showing vacuolar interface dermatitis with atrophy, suggestive of subacute lupus erythematosus. Blood work revealed positive antinuclear antibody, anti-ribonucleoprotein antibody, Sjogren Anti-SS-A and positive histone antibody. Given the worsening rash, positive labs, and cenobamate as the only changed drug several months before initial onset, she was diagnosed with drug-induced subacute cutaneous lupus erythematous and her cenobamate was discontinued. To the best of your knowledge, this is the first reported case of a medication in the carbamate family leading to drug induced subacute cutaneous lupus erythematosus.
