A case of elastosis perforans serpiginosa.

A 17-year-old white boy with no underlying connective tissue disorders presented with flat-topped annular plaques, with slight central atrophy on the bilateral neck. Results from histopathology revealed changes consistent with elastosis perforans serpiginosa (EPS). The idiopathic form of EPS occurs rarely in children. We report a patient with this rare pediatric diagnosis and review the literature.
