      Abstract

      Twenty patients aged between 2 years and 17 years (mean 9 years) with pigmented birthmarks, mainly of the head and neck, were treated with the PLDL-1 laser (Pigmented Lesion Dye Laser—Candela Corporation, Wayland, Massachusetts, USA) which emits light with a wavelength of 510 nanometers and a pulse duration of 300±50 nano-seconds.
      Nine patients (45%) showed excellent results after a test-patch was performed. Two patients (10%) showed some lightening of colour after initial test-patch. Six patients (30%) showed no improvement and 3 patients (15%) showed some hyperpigmentation at the test-patch sites which had not disappeared at 6 months follow-up.
      There was no change in the clinical behaviour at 6 months follow-up and no evidence of scarring was encountered.
