title: Paradoxical adverse effects of anti-TNF-alpha treatment: onset or exacerbation of cutaneous disorders.
abstract: TNF-alpha antagonists have been shown to be very effective for the treatment of various rheumatic and nonrheumatic diseases, including psoriasis, and for off-label use in other inflammatory and immune-mediated disorders. However, the increasing use of these agents has led to the recognition of several paradoxical cutaneous adverse effects. New onset or exacerbation of cutaneous psoriasis, cutaneous vasculitis and sarcoidosis have been described. Further characterization and more precise diagnosis of these adverse events are warranted to provide further insights into the pathogenic mechanisms involved and to optimize their management. Herein, we present a review of the different clinical patterns of these paradoxical cutaneous adverse disorders, and we propose recommendations for their management.
