Tratamiento con Pulsed Dye Laser de mancha de vino oporto: seguimiento a 10 años / Treatment with Pulsed Dye Laser of wine stain Porto: 10-year follow-up

Las manchas de vino de oporto son un tipo de malformación capilar que afecta del 0,3 al 0,5% de la población. Están presentes desde el nacimiento como máculas o placas eritematosas en la piel o mucosas. Sin tratamiento, las lesiones tienden a oscurecerse con la edad, tornándose rojizas o color púrpura, y pueden desarrollar engrosamiento nodular o un granuloma piógeno asociado. Los tratamientos con láser proporcionan mejoría mediante la destrucción selectiva de la vasculatura. Se han utilizado una variedad de láseres vasculares selectivos, pero el tratamiento de primera elección es el láser de colorante pulsado. Los mejores resultados se obtienen cuando el tratamiento es instaurado tempranamente. (AU)

Port wine stains are a type of vascular malformation that affects 0.3% to 0.5% of the population. They are present from birth as erythematous macules or plaques on the skin or mucous membranes. Without treatment, these lesions tend to darken with age, becoming reddish or purple and may develop nodular thickening or an associated pyogenic granuloma. Laser treatments might provide an improvement by selective destruction of the vasculature. A variety of selective vascular lásers may be employed, with the pulsed dye laser as the gold standard treatment. Better results are obtained when the treatment is established early. (AU)

Nail psoriasis treated with pulsed dye laser

Abstract: Nail changes are present in about 50% of psoriasis patients and tend to be refractory to conventional treatments. Pulsed dye laser has emerged as an alternative therapy. Our aim is to evaluate the efficacy of pulsed dye laser in nail psoriasis and the impact of treatment on quality of life. Fourteen patients were treated in monthly sessions for three months. The outcome assesment was made by the Nail Psoriasis Severity Index (NAPSI). The median improvement in the scores of the overall NAPSI, nail bed NAPSI, and nail matrix NAPSI were 44.2% (P = 0.002), 50% (P = 0.033) and 65.1% (P = 0.024), respectively.

Para el manejo de la malformación capilar facial, el láser de colorante pulsado es el que ha demostrado mayor eficacia. Presentamos el caso de una niña con síndrome de Sturge-Weber, tratada con láser de colorante pulsado, con muy buenos resultados estéticos.

Atypical Angioma Serpiginosum

Angioma serpiginosum is an uncommon, acquired vascular nevoid disorder with capillary dilation and proliferation in the papillary dermis. The eruptions are asymptomatic and characterized by grouped, erythematous to violaceous, serpiginous and punctate macules. The condition usually appears in females during adolescence on unilateral lower extremities and the buttocks. We report a rare case with a late onset and atypical distribution of lesions in a 48-year-old female patient who had groups of punctate lesions on her left foot for four to five years. Histopathological examination showed hyperkeratosis and multiple dilated and proliferated capillaries in the papillary dermis. Inflammation and extravasation of red blood cells were not found. According to the clinical and pathological findings, we established a diagnosis of angioma serpiginosum. She was treated with a pulsed dye laser, and the angiomatous lesions subsequently improved.
