Tocilizumab-induced psoriatic eruption : a case report and a case-based review.

To conclude, in case of TCZ-induced psoriatic eruption and in light of the published cases, we suggest using topical steroids and reassessing the patient 4 weeks later. If no healing is obtained, we suggest stopping TCZ, and treating the underlying disease with another drug. When no other drug is available, while waiting for more data regarding the value of IL-6 levels, it can be discussed to increase TCZ regimen, as it has been successful for 2 authors. Efficacy assessment of the chosen attitude should not take place before 4 weeks.
