Acne rosacea is a relatively common disease, which usually manifests in the third and fourth decades of life. It has an inflammatory condition (Papules and pustules) associated with telangiectasis, erythema and sometimes rhinophyma at the end stage of the disease. Pulsed-dye-laser (PDL), which has been designed for treatment of vascular lesions, may be used in treatment of acne rosacea. We present a 64-year-old man with a chronic and resistant form of acne rosacea, who underwent multiple sessions of PDL (Candela, Scleroplus) with pulse duration=1500?s, 600nm long waves and 13-14 J/cm² with 6-8 weeks intervals. Clinical follow up showed not only a reduction in edema, erythrosis and telangiectasis but also a control of inflammatory components and regression of rhinophyma. The patient didn’t take any medication during treatment and follow up period. PDL (585nm, 6-7.5 J/cm²) treatment of telangiectasis associated with rosacea had already be known, however it is the first report of successful management of chronic and resistant acne rosacea with PDL treatment by different parameters.
