Objective:

To report a case of refractory acrodermatitis continua of Hallopeau (ACH) successfully treated with local injections of an IL-17 inhibitor, highlighting the significance of avoiding immune drift.

Key Findings:
  • Local injections of Xeligekimab led to significant improvement in skin lesions, with metrics indicating substantial clinical benefit.
  • No recurrence of eczematous eruptions or systemic adverse reactions were observed.
  • PPPASI decreased from 14.4 to 1.2, DLQI from 24 to 4, and NAPSI from 160 to 60 over 16 weeks, demonstrating effective treatment.
Interpretation:

Local administration of an IL-17 inhibitor may effectively control ACH while preventing systemic immune imbalance, suggesting a promising avenue for future treatments.

Limitations:
  • This is a single case report and requires further validation in larger, more diverse studies.
Conclusion:

Local injection of IL-17 inhibitors presents a novel treatment approach for refractory ACH, warranting further research to validate these findings.
