Hypohidrotic ectodermal dysplasia: a case report.

Ectodermal dysplasias represent a large and complex group of diseases comprising more than 170 clinical conditions. They are caused by impaired development of the ectodermal appendages and characterized by a primary defect in at least one of the following tissues: nails, hair, sweat glands, or teeth. Ectodermal dysplasia has emotional consequences for affected individuals at early ages.
