Although available data are conflicting, psoriasis seems to be associated with an increased baseline risk of malignancy. In addition, some antipsoriatic systemic treatments have been associated with risk of malignancy. There is not enough data on the association of interleukin (IL)-17 and IL-23 inhibitors with malignancy rate, but there have been no cases reported so far. Secukinumab is a recombinant human monoclonal immunoglobulin G1/κ antibody that selectively targets IL-17A; it was demonstrated to be effective and safe for the treatment of moderate to severe psoriasis that may be appropriate in frail subjects, as patients previously experienced malignancy, as in the case reported.
