[Acquired naevus flammeus (Fegeler syndrome)].

We report the development of an acquired nevus flammeus following a ski accident. This disorder was first described by Fegeler 1949, who reported the case of a 43-year-old soldier who acquired a nevus flammeus in the face following a cranial trauma. Since then, a number of similar case reports have been published. Differential diagnosis is discussed, such as the unilateral nevoid teleangiectasia syndrome, eruptive nevoid teleangiectasia and eruptive spider nevi.
