Idiopathic atrophy of the nails: a possible hereditary association.

Idiopathic atrophy of the nails has been described as an acquired condition of childhood wherein the changes may lead to permanent loss with scarring of the nail bed. Three patients with idiopathic atrophy are described here, two of whom are siblings, ages 9 and 11 years. The authors suggest that all family members of patients with this condition be examined for possible involvement.
