RESUMO
Objective To observe the effect of E light combined with 595 nm pulsed dye laser in patients with erythromelanosis follicularis of face and neck. Methods The clinical data of 44 patients with erythromelanosis follicularis of face and neck from 2015 to 2017 in Dalian Dermatosis Hospital were retrospectively analyzed. Among the patients, 22 patients were treated with 595 nm pulsed dye laser (control group) and 22 cases were treated with E light combined with 595 nm pulsed dye laser (treatment group). Efficacy was assessed 1 month after treatment, including telangiectasia, pigmentation and follicular papule. Results The total effective rates of telangiectasia, pigmentation and follicular papule in treatment group were significantly higher than those in control group: 86.4% (19/22) vs. 68.2% (15/22), 54.5% (12/22) vs. 9.1% (2/22) and 50.0% (11/22) vs. 13.6% (3/22), and there were statistical differences (P＜0.05). No significant adverse reactions occurred during and after treatment in 2 groups. Conclusions E light combined with 595 nm pulsed dye laser is better and safer than 595 nm pulsed dye laser alone in the treatment of erythromelanosis follicularis of face and neck.
