Treatment of angioma serpiginosum using a pulsed tunable dye laser

Angioma serpiginosum (AS) is a rare vascular naevoid disorder due to ectatic dilation of capillaries in the papillary dermis. The condition is found almost exclusively in females who have grouped erythematous punctate lesions usually on the lower limbs or buttocks, which may be unsightly. We report five patients with AS treated using a Candela SPLT1 pulsed tunable dye laser. All patients had a good to excellent response. The lesion resolved in one patient, virtually resolved in two and is considerably improved in a further patient in whom treatment is continuing. In one patient, the angiomatous lesion improved but the patient developed hyperpigmentation at the treatment site and the treatment has been temporarily suspended. The results suggest that treatment using the pulsed dye laser is very effective for AS and, in most patients, produces an excellent cosmetic result.
