<p> Background and aims : Primary localized cutaneous amyloidosis (PLCA) is a persistent dermatological disorder characterized by the accumulation of amyloid deposits within the dermal papillae, resulting in pigmentation alterations, pruritus, and textural modifications of the skin.

Our study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for systematic reviews and meta-analyses. Results: Based on our inclusion criteria, 16 studies with 432 patients were included, assessing fractional CO₂ laser, Nd: YAG laser, Er: YAG laser, microneedling, and phototherapy for PLCA treatment. Fractional CO₂ laser effectively improved pigmentation and pruritus, especially when combined with corticosteroids or vitamin C.

摘要

Background and aims : Primary localized cutaneous amyloidosis (PLCA) is a persistent dermatological disorder characterized by the accumulation of amyloid deposits within the dermal papillae, resulting in pigmentation alterations, pruritus, and textural modifications of the skin. Given the lack of a standardized treatment for this condition, this review aims to evaluate the efficacy and safety of various procedural modalities for PLCA management. Methods: PubMed/Medline, Scopus, and Web of Science were systematically searched until August 25th, 2024. The study selection was restricted to English-language clinical studies, excluding case reports and case series. Our study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for systematic reviews and meta-analyses. Results: Based on our inclusion criteria, 16 studies with 432 patients were included, assessing fractional CO₂ laser, Nd: YAG laser, Er: YAG laser, microneedling, and phototherapy for PLCA treatment. Fractional CO₂ laser effectively improved pigmentation and pruritus, especially when combined with corticosteroids or vitamin C. Nd: YAG and Er: YAG lasers demonstrated favorable outcomes, with combination therapies enhancing efficacy. Microneedling and phototherapy (PUVA/UVB) also showed benefits, with PUVA being superior for pruritus. Conclusion: Fractional CO₂ laser, especially with corticosteroids or vitamin C, showed the most effective results for pigmentation, pruritus, and amyloid reduction in PLCA. Nd: YAG and Erbium lasers, microneedling, and phototherapy also demonstrated benefits. However, further comparative clinical trials are needed to determine the most effective approach and establish standardized treatment protocols.
