This case series highlights the potential utility of non-ablative fractional laser and pulse-dye laser therapy to improve scar hypertrophy, pain, erythema, and appearance in healed pyoderma gangrenosum lesions. When initiated after systemic inflammatory disease is adequately controlled, the risk of pathergy appears minimized. Although larger studies are needed, this series highlights a promising approach to scar reduction in pyoderma gangrenosum.
Vague et al. (2026) studied this question.
