Fractional CO₂ Laser for Primary Cutaneous Amyloidosis

Clinical and Ultrastructural Evaluation of Fractional CO₂ Laser in the Treatment of Primary Cutaneous Amyloidosis: A Randomized, Controlled Clinical Study

Source: ClinicalTrials.gov · Last updated 11 Sept 2026

Brief summary (registry, in English)

This randomized, controlled clinical study will evaluate the clinical and ultrastructural effects, efficacy, and safety of fractional CO₂ laser in patients with primary cutaneous amyloidosis. Twenty-two eligible patients will be randomly allocated in a 1:1 ratio to receive either three fractional CO₂ laser sessions at 4-week intervals or no active laser treatment (control group). The primary outcome will be the change in the Amyloidosis Severity Score from baseline to one month after the final laser session, with secondary assessments including dermoscopic findings, transmission electron microscopy findings, pruritus severity, patient satisfaction, and adverse events.
