The median time to psoriasis onset or worsening was 13\u2009months (3\u201383\u2009months) under continuous treatment with BCDT. Topical therapies were effective in most cases, but a change of MS treatment or initiation of psoriasis-specific immunotherapies, including the interleukin-17A-antibody secukinumab, was required in four patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Psoriasis onset or worsening during BCDT is rare.
