Unusual cutaneous manifestations of anhidrotic ectodermal dysplasia--a case report.

Congenital ectodermal dysplasia is a group of familial disorders that affect tissues and organs of ectodermal origin to varying degrees. Our patient with classical X-linked anhidrotic ectodermal dysplasia (AED) showed unusual skin manifestations including cafe-au-lait spots on the face, neck, buttock, and lumbo-sacral region; depigmentation of mucous membrane of the lower lip, buccal cavity, and left arm; absence of tragii; plantar keratoderma; and kyphosis of lower cervical and upper thoracic spines which have not been previously reported in the world literature.
