Cutaneous lichen planus (LP) is an inflammatory skin disease characterized by an interface dermatitis with lymphocyte infiltration and keratinocyte (KC) cell death. The aim of this study was to investigate the immunopathogenesis of LP and assess the underlying mechanisms that drive the interface dermatitis reaction. We first performed single-cell RNA sequencing on lesional skins from patients with LP compared with healthy control skins and demonstrate that LP skin is imprinted by a type I IFN-rich environment.

Objectives: To describe the characteristics, treatment and outcome of isolated ANCA-associated scleritis at diagnosis compared with idiopathic scleritis with negative ANCA tests.
Methods: This retrospective multicentre case-control study was performed within the French Vasculitis Study Group (FVSG) network and in three French tertiary ophthalmologic centres. Data from patients with scleritis without any systemic manifestation and with positive ANCA results were compared with those of a control group of patients with idiopathic scleritis with negative ANCA tests.
