Psoriasis and oncology: is there a way out?

In severe psoriasis, systemic therapy is required, but the number of studies on the use of biologics drugs in patients with existing or history of cancer is limited, which creates difficulties in prescribing this group of drugs. The presented clinical case demonstrates the interdisciplinary interaction between a dermatologist and an oncologic surgeon. A patient diagnosed with psoriasis, psoriatic arthritis, and basal cell carcinoma underwent successful therapy with the IL-23 inhibitor risankizumab, which has demonstrated high safety and efficacy in the treatment of psoriasis, and surgical removal of the basal cell carcinoma by Mohs micrographic surgery. For patients with psoriasis and an existing or history of cancer, multidisciplinary collaboration is required to determine optimal therapeutic tactics.
