title: Idiopathic 20-nail dystrophy.
abstract: Twenty-nail dystrophy is a rare disease, typically with all 20 nails affected, which normally occurs as an idiopathic condition in childhood but can be linked to other diseases. We report a case of a 7-year-old girl with a 3-year history of 20-nail dystrophy and no associated diseases or family history of skin or nail diseases. She was followed and treated conservatively and, after 6 years of follow-up, we found a marked improvement and almost full resolution of her nail dystrophy. The aim of this report is to show that idiopathic 20-nail dystrophy in children is a self-limiting condition and thus can be treated conservatively.
