ABSTRACT

Observation:

Twenty-nail dystrophy is a self-limiting, idiopathic, non-congenital nail disorder. Clinically, all nails are involved uniformly and simultaneously. Although commonly being idiopathic, twenty-nail dystrophy has been reported to be associated with the several diseases including vitiligo, alopecia areata, alopecia universalis, ichthyosis vulgaris, selective Ig A deficiency and inkontinentia pigmentia. This paper reports a case diagnosed as idiopathic twenty-nail dystrophy.
