[Angioma serpiginosum following the lines of Blaschko--an effective treatment with the IPL technology].

Angioma serpiginosum, first described by Hutchinson in 1889, is a rare benign vascular nevus with dilatation and proliferation of the capillaries in the upper dermis. A 15-year-old boy presented with an angioma serpiginosum on the right side of the body following the lines of Blaschko. Both the clinical pattern and the appearance in a male are unusual. Treatment with IPL technology (intense pulsed light), which emits polychromatic light from a high-intensity flashlamp, proved to be an effective approach.
