Lichenoid Drug Eruption Induced by Teriflunomide.

ABSTRACT

Lichenoid drug eruptions are a type of skin reaction that is caused by medication and mimics idiopathic lichen planus. Various medications have been known to cause lichenoid drug eruptions, such as antibiotics, anti-convulsants, anti-diabetics, anti-malarials, anti-tubercular drugs, anti-hypertensives, psychiatric drugs, chemotherapeutic agents, diuretics, heavy metals, and non-steroidal anti-inflammatory drugs. Various cutaneous side effects have been reported in association with teriflunomide. We present the case of a patient who developed a lichenoid eruption because of teriflunomide. The dermatologists and neurologists should be aware of these skin side effects.
