A Case of Palmoplantar Pustulosis Induced by Certolizumab Pegol: New Anti-TNF-alpha Demonstrates the Same Class Effect.

The authors hereby report a case of palmplantar pustular psoriasis in a patient with rheumatoid arthritis treated with etanercept. The condition responded to topical steroids but re-occurred upon treating the patient with certolizumab pegol. This strongly suggests that the development of de novo psoriasis is a class effect.
