Abstract

Multiple lentigines confined to psoriatic plaques is a rare entity, which is more frequently recognized after the use of systemic biologic agents for psoriasis therapy. Although this phenomenon was previously accepted as a postinflammatory reaction, recent observations suggest psoriasis-related cytokines and their efficient supression by biologic agents strongly associate with melanogenesis and melanocytic proliferation. Hereby, we report a patient who developed multiple lentigines arising in resolved psoriatic plaques induced by infliximab and review similar cases reported in the literature induced after biologic treatments of psoriasis.
