Giant cell arteritis associated with scalp, tongue or lip necrosis: A French multicenter case control study.

Background: Scalp, tongue and/or lip necrosis are rare complications of GCA.

Objectives: To describe characteristics and outcome of patients with giant cell arteritis (GCA) -related scalp, tongue and/or lip necrosis.

Methods: A retrospective nationwide multicenter study included 20 GCA patients with scalp, tongue, and/or lip necrosis diagnosed between 1998 and 2021 and 80 GCA control patients matched for age, sex and management period.

[Severe systemic vasculitis induced by ibrutinib].

Introduction: The specific cutaneous toxicity of Bruton's tyrosine kinase inhibitors is poorly described. We report a case of severe systemic vasculitis induced by ibrutinib.

Observation: A 73-year-old woman with chronic lymphocytic leukemia was treated with ibrutinib.

Anti-BP180 IgG antibody ELISA values correlate with adverse pregnancy outcomes in pemphigoid gestationis.

Background: Adverse pregnancy outcomes (APO) occur in 35% of patients with pemphigoid gestationis (PG). No biological predictor of APO has been established yet.

Objectives: To assess a potential relationship between the occurrence of APO and the serum value of anti-BP180 antibodies at the time of PG diagnosis.
