Abstract
Acrodermatitis continua of Hallopeau (ACH) is a rare pustular psoriasis subtype, characterized by recurrent sterile pustules on digits, progressive nail deformation and atrophy. ACH is often refractory to different therapeutic modalities, presenting challenges in clinical practice. Emerging evidence indicates that elevated IL-17 levels modulate keratinocyte proliferation and immune cell infiltration, contributing to ACH pathogenesis and representing a promising therapeutic target. Herein, we presented a case of ACH successfully treated with vunakizumab, China's first self-developed anti-IL-17A monoclonal antibody, and reviewed publications reporting IL-17 targeted therapies for ACH, highlighting the potential benefit of IL-17 targeted therapy in ACH management.
