[Monoclonal antibodies for inflammatory, autoimmune and oncological skin diseases].

In 1997 rituximab, a genetically engineered chimeric monoclonal antibody (mAb) targeting CD20 expressed on B cells was approved for treatment of non-Hodgkin's lymphoma. Since then, pharmacological improvements combined with increased knowledge on the immunopathogenesis of diseases led to the development of specific mAb targeting different antigens (e.g., interleukins or transmembrane receptors). This approach reshaped the therapeutic methodology in many fields, including dermatology. Nowadays, the treatment of frequent and possibly impairing inflammatory disorders such as psoriasis, atopic dermatitis or hidradenitis suppurativa have different mAbs approved for both adult and pediatric patients. This class of drugs often shows a more favorable outcome and a better safety profile than routine immunosuppressants, such as steroids and steroid-sparing substances. For many years mAbs also represented a pillar of oncological treatment for severe diseases such as malignant melanoma or Merkel cell carcinoma. This review summarizes the current knowledge on already approved and promising new mAbs for the treatment of inflammatory and oncological skin diseases.
