Treatment of Erythromelanosis Follicularis Faciei Et Colli With a 595-Nm Pulsed Dye Laser

This study reports on the treatment of erythromelanosis follicularis faciei et colli (EFFC) using a 595-nm pulsed dye laser (PDL) in three patients, showing significant improvement in symptoms such as telangiectasia, hyperpigmentation, and follicular papules. The patients, aged 16, 18, and 27, experienced notable reductions in facial redness and skin roughness after three treatment sessions, with minimal adverse effects like transient purpura and swelling. Follow-up periods ranged from 3 months to 4 years, revealing almost no recurrence of symptoms. Despite the small sample size, the study suggests that 595-nm PDL is an effective and safe treatment for EFFC, warranting further investigation.
