Onychodystrophy in lichen striatus.

Lichen striatus is a common childhood eruption, but only rare reports link cutaneous manifestations and onychodystrophy. We report a case of lichen striatus and onychodystrophy in a 12-year-old girl, only the eighth such patient in the dermatologic literature. Nail changes may precede the rash of lichen striatus and should be considered in the differential diagnosis of isolated nail dystrophy in children.
