For the primary analysis, this study examines the risk of melanoma and nonmelanoma skin cancers: squamous cell carcinoma and basal cell carcinoma in people diagnosed with vitiligo. It also examines actinic keratoses. In secondary analysis, this study examines the prevalence of skin cancer in people diagnosed with vitiligo compared to matched controls.
This study also examines whether the susceptibility to melanoma and nonmelanoma skin cancer may vary between different patient subgroups, e.g. ethnicity, those who undergo phototherapy or treatment with the new targeted biologic immunosuppressive therapies.
