[Acquired nevus flammeus (author's transl)]

We report about two patients with acquired nevus-flammeus-like skin changes. In one case the skin alterations spread all over, in the other case the mole - although it became bigger - was restricted to the right foot. The first patient was pregnant, the second in puberty. There were no hints to any traumas before. Biopsies revealed findings as in nevus flammeus.
