Palmar pustular psoriasis associated with teriflunomide treatment

Abstract

Background Cutaneous adverse effects of Teriflunomide have been rarely reported.

Objective and methods We report a relapsing remitting multiple sclerosis patient that developed palmar pustular psoriasis within one month of teriflunomide initiation.

Results Our patient required discontinuation of teriflunomide due to frequent recurrence of pustules with continuous need of local steroid treatment and resolved completely after teriflunomide discontinuation.

Conclusion Pustular psoriasis can be triggered by medications but has not been previously reported in association with teriflunomide treatment, to the best of our knowledge.
