Background: The treatment of vitiligo can be challenging. Up‐to‐date agreed consensus recommendations on the use of topical and systemic therapies to facilitate the clinical management of vitiligo are currently lacking.Objectives: To develop internationally agreed‐upon expert‐based recommendations for the treatment of vitiligo.Methods: In this consensus statement, a consortium of 42 international vitiligo experts and four patient representatives participated in different online and live meetings to develop a consensus management strategy for vitiligo. At least two vitiligo experts summarized the evidence for different topics included in the algorithms. A survey was then given to a core group of eight experts to resolve the remaining issues. Subsequently, the recommendations were finalized and validated based on further input from the entire group during two live meetings.Results: The recommendations provided summarize the latest evidence regarding the use of topical therapies (steroids, calcineurin inhibitors and Jak‐inhibitors) and systemic therapies, including steroids and other systemic immunomodulating or antioxidant agents. The different modalities of phototherapies (NB‐UVB, photochemotherapy, excimer devices and home phototherapy), which are often combined with other therapies, are also summarized. Interventional approaches as well as depigmentation strategies are presented for specific indications. Finally, the status of innovative and targeted therapies under development is discussed.Conclusions: This international consensus statement culminated in expert‐based clinical practice recommendations for the treatment of vitiligo. The development of new therapies is ongoing in vitiligo, and this will likely improve the future management of vitiligo, a disease that still has many unmet needs.

Background: The treatment of vitiligo can be challenging and depends on several factors such as the subtype, disease activity, vitiligo extent, and treatment goals. Vitiligo usually requires a long‐term approach. To improve the management of vitiligo worldwide, a clear and up‐to‐date guide based on international consensus with uniform stepwise recommendations is needed.Objectives: To reach an international consensus on the nomenclature and to develop a management algorithm for the diagnosis, assessment, and treatment of vitiligo.Methods: In this consensus statement, a consortium of 42 international vitiligo experts and four patient representatives participated in online and live meetings to develop a consensus management strategy for vitiligo. At least two vitiligo experts summarized the evidence of topics included in the algorithms. A survey was utilized to resolve remaining issues among a core group of eight experts. Subsequently, the unanimous recommendations were finalized and validated based on further input from the entire group during two live meetings.Results: The algorithms highlight the importance of shared decision‐making. Dermatologists are encouraged to provide patients with detailed explanations of the prognosis and expected therapeutic outcomes based on clinical examination. The treatment goal should be discussed and clearly emphasized to patients given the different approaches for disease stabilization and repigmentation. The evaluation of disease activity remains a cornerstone in the tailor‐made approach to vitiligo patients.Conclusions: These new treatment algorithms are intended to guide clinical decision‐making in clinical practice. Promising novel therapies for vitiligo are on the horizon, further highlighting the need for reliable outcome measurement instruments and greater emphasis on shared decision‐making.

Summary: Koebner’s phenomenon (KP) has been observed in a number of skin diseases, including vitiligo. Its clinical significance in vitiligo with respect to disease activity and course is still debatable, while its relevance for surgical techniques has been demonstrated in some reports. We present a literature review on the currently known facts about KP in vitiligo, including details of clinical, experimental, and histopathological changes. The consensus view is that there are still no methods to define and assess KP in vitiligo. A new classification is proposed to allow an evaluation of KP in daily practice or in experimental studies. However, many unanswered questions still remain after redefining KP in patients with vitiligo. Active research focusing on KP in vitiligo may not only provide unexpected clues in the pathogenesis of vitiligo but also help to tailor novel therapies against this chronic and often psychologically devastating skin disease.
