Treatment of Necrobiosis Lipoidica in the left forearm with association of Intense Pulsed Light and Erbium-Yag Laser 2940nm

Necrobiosis Lipoidica (NL) is a granulomatous dermatosis, mainly affecting people with diabetes due to collagen degeneration. Although there are different treatments, all have little response. Among the options, the Intense Pulsed Light (IPL) and the Laser Erbium-YAG enhance the production and remodeling of the collagen treating the atrophy, besides reducing the erythema by the coagulation of blood vessels. We report a case of a 24-year-old woman with type I Diabetes Mellitus who underwent NL treatment on her left forearm in seven sessions with the association of IPL and 2940 nm Erbium-YAG laser. We observed improvement in central atrophy and erythema.
