Dermatofibromas treated with pulsed dye laser: Clinical and dermoscopic outcomes.

Dermatofibroma (DF), a common benign skin tumour, sometimes requires treatment either because of cosmetic concern or for associated symptoms. However, no effective treatment with optimal cosmetic outcomes has been reported. An effective and safe therapeutic option could be treatment with pulsed dye laser (PDL). Twenty-two DFs in 15 patients were treated with PDL at 595-nm wavelength, using a spot size of 7 mm, a pulse duration of 2 ms and a fluence of 11 J/cm(2) with 2 or 3 stacked pulses. Clinical and dermoscopic photographs were taken before and after therapy. Global clinical improvement was higher than 50% in 12 lesions. Patient satisfaction assessment showed 73% of patients as satisfied or very satisfied. All lesions showed changes from the previous dermoscopic pattern. We consider that PDL could be a safe, palliative treatment as it is well accepted by patients and has a better cosmetic outcome than surgical excision.
