In Korean patients with vitiligo, researchers quantified the incidence of melanoma and nonmelanoma skin cancer (NMSC) and compared it with matched nonvitiligo controls. A retrospective matched cohort study was conducted with 131,245 cases of incident vitiligo and 2,624,900 age- and gender-matched (1:20) controls at index date selected from the Korean National Health Insurance database between January 2005 and December 2017. Vitiligo patients were followed up for a mean duration of 6·34 years vs a follow-up period of 6·27 years for matched controls. Data reported that ultraviolet (UV) treatment-adjusted HR for melanoma in vitiligo patients was 3·32 and 1·29 for NMSC.
