title: Twenty-nail dystrophy of alopecia areata.
abstract: We describe here a patient with dystrophy of all 20 nails, which has persisted for five years after the resolution of alopecia areata. We feel that the term "20-nail dystrophy" is best used to describe a clinical entity that can have several causes.
