Abstract

We describe a patient with psoriasis who developed pyoderma gangrenosum while on treatment with brodalumab, an anti-interleukin (IL)-17 receptor monoclonal antibody. Genetic analyses revealed heterozygous polymorphisms within the promoter region of the IL-6 (promoter polymorphism –174 G/C) and IL-10 genes (promoter polymorphism –1082 A/G).
