[Cutaneous lupus erythematosus induced by terbinafine]

Cutaneous lupus erythematosus can be induced or precipitated by a variety of drugs. Among the cutaneous variants of lupus, subacute cutaneous lupus erythematosus is the one most often associated with drug intake. The time lag between drug intake and skin eruption makes the clinical association less obvious, and the condition is often overlooked. We report on a 50-year-old woman with previously diagnosed systemic lupus erythematosus who had a severe cutaneous flare-up seven weeks after starting treatment with terbinafine for suspected onychomycosis.
