Congenital onychoheterotopia involving multiple toe nails.
Onychoheterotopia is an uncommon condition in which nail tissue is found beyond the common nail unit of the digits of the hands and feet, most often on the fifth digit of the hand. It represents an extra and independent nail that can be present either congenitally, or more commonly, acquired following trauma. The exact pathogenesis of the congenital type is undetermined. We report a 25-year-old male with multiple congenital ectopic nails of the toes since birth, which has not been reported before.
