Pyoderma gangrenosum is an autoinflammatory disease, characterized by relapsing, painful ulcers of the skin. Treatment of PG is difficult. Patients suffer from long hospitalization, pain and reduced life quality. New therapeutic strategies are needed. Immunohistological staining show a high amount of IL-17 in PG. IL-17+ immune cells were located in proximity to cellular damage, indicating an involvement in the pathogenesis. Targeting IL-17 with neutralizing IL-17 antibodies seems promising. M
