Mortality Risks among Patients with Lichen Planus: A Korean Nationwide Population-Based Cohort Study

Lichen planus (LP) is a chronic inflammatory disease affecting the skin and mucous membranes ( Tziotzios et al., 2018 Tziotzios C. Lee J.Y.W. Brier T. Saito R. Hsu C.K. Bhargava K. et al. Lichen planus and lichenoid dermatoses: clinical overview and molecular basis. J Am Acad Dermatol. 2018; 79: 789-804 Abstract Full Text Full Text PDF PubMed Scopus (98) Google Scholar ). Like inflammatory dermatoses such as psoriasis and atopic dermatitis, the etiology and associated diseases of LP-related to the immune response have been studied; however, the mortality risk is unknown. This study analyzed the all-cause and cause-specific mortality of LP over a 12-year period.
