Anetoderma treated with combined 595-nm pulsed-dye laser and 1550-nm non-ablative fractionated laser.

Anetoderma is a skin disorder characterized by a focal loss of dermal elastic tissue whereby patients present with soft, depressible lesions. We postulated that a series of combination treatment using the 595-nm pulsed dye laser (PDL) and the 1550-nm non-ablative fractionated laser (NAFL) would improve the anetoderma lesions. Our patient with biopsy proven anetoderma received 3 treatments with a combination of 595-nm PDL and 1550-nm NAFL spaced 3 weeks apart. Skin biopsies were performed at baseline and immediately prior to the third treatment. Stains for hematoxylin and eosin and Verhoeff Van Gieson (VVG) were performed. Improvement in lesion color, texture, and overall appearance was noted after the second treatment and continued following the third treatment. Post-treatment VVG staining demonstrated an increase in dermal elastin fibers and a decrease in elastin fiber fragmentation. Thus, the combination of 595-nm PDL and 1550-nm NAFL should be considered as a treatment modality for anetoderma.
