Pulsed dye and carbon dioxide lasers have been applied in dermatofibroma with clinical improvement. We treated 23 dermatofibromas two times at a 4-week interval with Q-Switched alexandrite laser 755nm (7.5J/cm2, 3mm, 50ms). V Beam pulsed dye laser with a wavelength of 595nm was used for the residual erythema (10-11J/cm2, 7mm, 1.5ms). A partial attenuation of brown colour was observed in 9 patients and complete disappearance of brown colour in 14 patients. Patient satisfaction was very high. Fifteen patients felt a decrease in hardening of dermatofibroma after treatment. A pigment network in dermoscopy was observed in all patients before treatment and no one after treatment. A combined treatment using both V Beam pulsed dye laser and Q-Switched alexandrite laser may be a therapeutic option to reduce the aesthetic effect of dermatofibroma with a high patient satisfaction and good cosmetic outcomes.
