Erosive lichen planus: an unmet disease burden.

Objectives: To explore the demographic and clinical profile of erosive lichen planus (ELP) across multiple ethnicities within a single cohort, deepening our understanding of disease severity, progression and outcomes.

Methods: A longitudinal retrospective cohort study of ELP patients in the ethnically diverse population of East London was carried out, profiling ELP ( = 57) against the milder reticular lichen planus (RLP) ( = 35).

Results: A higher prevalence of ELP was observed in white populations compared to other ethnicities.
