Fingolimod-related viral infections have been described on several occasions since its introduction in 2010. We hereby add a report on an otherwise immunocompetent, 18-year old Caucasian man with relapsing-remitting multiple sclerosis who developed a protracted and extensive molluscum contagiosum (MC) virus infection shortly after being started on fingolimod. Wide-spread cutaneous MC infections in adult patients are considered indicative of underlying immunosuppression. Neurologists prescribing fingolimod ought to be aware of a possibly increased risk of MC, but also need to know about its relative benignity, lack of extra-cutaneous complications, and adequate treatment options.
Keywords: Fingolimod; immunosuppression; molluscum contagiosum; poxvirus.
